feat: add Go worktree and verification backend

[gnanam1990]

Summary

• add a Go worktree isolation backend with deterministic task names, safe worktree path handling, and reusable detached worktree preparation
• add a Go verification backend that detects repository checks, runs filtered verification plans, redacts command output, and reports structured pass/fail/error summaries
• wire the new backend into the CLI through zero worktrees prepare, zero verify, and zero exec --worktree / --worktree-dir with conflict validation

Local validation

• go test -count=1 ./internal/worktrees ./internal/verify ./internal/cli
• go test -count=1 -p 1 ./...
• npx --yes bun run typecheck
• npx --yes bun test ./tests --timeout 15000
• npx --yes bun run build
• npx --yes bun run smoke:build
• npx --yes bun run smoke:go
• ./zero verify --only go.test --timeout-ms 600000
• temp git repo smoke for ./zero worktrees prepare --json

Summary by CodeRabbit

• New Features

  • Added worktrees and verify CLI commands; "zero exec" gains --worktree and --worktree-dir. verify supports --only and timeout; both support --json output.
  • CLI can prepare isolated Git worktrees and run repository verification checks (Go/npm).

• CLI

  • Help text updated to list the new commands and options; output redacts sensitive workspace/worktree path segments.

• Tests

  • Added extensive tests for CLI, worktrees, and verify (success, failure, redaction, JSON).

Walkthrough

Adds Git worktree management and a local verification system, exposes worktrees prepare and verify CLI commands, extends zero exec with worktree flags, wires app dependencies, and adds unit/integration tests covering these flows.

Changes

Worktree & Verification Infrastructure

Layer / File(s)	Summary
Worktree Preparation Module internal/worktrees/worktrees.go, internal/worktrees/worktrees_test.go	Implements worktree creation/reuse under per-repo base dirs with name validation, repo-key derivation, Git runner abstraction, Prepare() and DefaultBaseDir(); tests cover create/reuse, cross-repo rejection, name/dir validation, and base-dir behavior.
Verification Plan Detection & Execution Module internal/verify/verify.go, internal/verify/verify_test.go	Adds verification data model, DetectPlan() (go.mod and package.json script detection) and Run() (pluggable Runner, timeout, per-check timing/output/status, redaction), with tests for detection, execution, filtering, unknown-only handling, and redaction.
CLI Workflow Commands internal/cli/workflows.go	Implements worktrees prepare and verify command runners and parsers, supports --json, --cwd, --name/--dir, --only, --timeout-ms, and provides text/JSON formatters and help text.
App Integration & Routing internal/cli/app.go, internal/cli/app_test.go	Extends appDeps with prepareWorktree, detectVerifyPlan, runVerify; wires defaults in defaultAppDeps; updates runWithDeps routing; injects missing deps in fillAppDeps; updates top-level and zero exec help text.
Exec Command: Worktree Support internal/cli/exec.go, internal/cli/exec_parse.go	Adds --worktree [name], --worktree=<name>, and --worktree-dir <dir> flags, validates --fork incompatibility and --worktree-dir dependency, and updates runExec to prepare/switch to a worktree when requested.
Integration Tests internal/cli/workflow_test.go	Integration tests for worktree prepare (success/error, text/JSON), verify (detection, --only, failure exit mapping, redaction), exec worktree integration and flag validation; uses stubs and asserts stdout/stderr/exit codes and JSON shapes.

Stub getwd here to keep this test hermetic.

TestRunWorktreesPrepareReportsErrors currently relies on default dependency behavior for cwd. Add a fixed getwd stub (like other tests) so this stays isolated from ambient process state if command pre-validation changes.

Proposed patch

 func TestRunWorktreesPrepareReportsErrors(t *testing.T) {
+	cwd := t.TempDir()
 	var stdout bytes.Buffer
 	var stderr bytes.Buffer
 	exitCode := runWithDeps([]string{"worktrees", "prepare", "--name", "bad"}, &stdout, &stderr, appDeps{
+		getwd: func() (string, error) { return cwd, nil },
 		prepareWorktree: func(context.Context, worktrees.Options) (worktrees.Result, error) {
 			return worktrees.Result{}, errors.New("not a git repository")
 		},

Inline comments:
In `@internal/cli/workflow_test.go`:
- Around line 222-256: The tests TestRunExecRejectsForkWithWorktree and
TestRunExecRejectsWorktreeDirWithoutWorktree currently only check exitCode and
stderr; add assertions that the captured stdout (the variable stdout passed into
runWithDeps) is empty for these usage error cases to ensure no unintended output
is written to stdout. Locate the two tests and after the existing stderr/assert
checks, add a check like if stdout.String() != "" { t.Fatalf("expected no
stdout, got %q", stdout.String()) } so the assertion references the stdout
buffer used in runWithDeps and ensures CLI UX guarantees are enforced.

In `@internal/cli/workflows.go`:
- Around line 124-133: When parsing flags in the loop (the branches handling arg
== "--name" and strings.HasPrefix(arg, "--name=")) and when assigning a
positional name (the later block around the positional handling at ~154-157),
check if options.name is already set to a non-empty value before overwriting; if
it is and the new incoming name is non-empty, return an error (fail fast)
instead of silently replacing it. Update the logic in the loop that calls
nextFlagValue and in the strings.HasPrefix("--name=") branch and the
positional-assignment code to perform this conflict check and return a
descriptive error if a second non-empty name is provided.

In `@internal/verify/verify.go`:
- Around line 273-279: The unknown slice is populated by iterating the map
allowed (nondeterministic order) causing unstable output; after building unknown
(from the loop over allowed and seen) sort it deterministically before returning
(e.g., call sort.Strings on unknown) so the function in
internal/verify/verify.go (the slice unknown computed from allowed and seen and
returned alongside filtered) always returns a stable ordering.

In `@internal/worktrees/worktrees.go`:
- Around line 95-102: When deciding to mark a target as reused (the reused check
returned by inspectTarget and setting result.Reused = true), first resolve the
target path (use filepath.EvalSymlinks) and confirm the existing folder is the
same Git repository as the expected one: obtain the repo identity from the
existing path (e.g., git -C <path> rev-parse --show-toplevel and/or git -C
<path> config --get remote.origin.url or read .git/config) and compare it to the
expected repository identity used to create the deterministic path; if the
identities differ, do not set result.Reused and proceed as if not reused. Ensure
this validation is applied in the same code paths that detect .git presence (the
logic around inspectTarget/target and the block that currently returns
result.Reused = true) so symlinked or pre-existing directories pointing to other
repos are rejected.

Blockers

• zero verify is a new diagnostic-output surface, but it serializes the resolved workspace path without redaction. In internal/cli/workflows.go, JSON mode writes the raw verify.Report directly and text mode prints root: + report.Root; verify.Report.Root comes from DetectPlan/resolveRoot unchanged. I reproduced this on latest head 45086327868fedd88f263710799e03bcc3571e53 by creating a temp workspace whose directory name contained an assembled OpenAI-shaped key. Both ./zero.exe verify -C <secret-dir> --json and text ./zero.exe verify -C <secret-dir> included the exact raw key in the root field. Please run the entire report through the central redaction path before both JSON and text formatting, and add a regression that covers secret-looking workspace paths. The same fix should cover zero worktrees prepare output too, because that command currently writes raw path/repoRoot values in JSON mode and formatWorktreeResult prints raw paths in text mode.

Non-Blocking

• CI was still finishing for the latest force-push when I posted this review: ubuntu/macOS/Performance/Zero Review had passed, Windows smoke was still pending on my latest check.

Looks Good

• The worktree backend validates task names, avoids path traversal through the worktree name, creates detached worktrees under a repo-keyed base directory, and refuses to reuse a path from a different git repository.
• The verify backend correctly detects Go/package-script checks, supports --only filtering, classifies pass/fail/error outcomes, applies per-check timeouts, and redacts command stdout/stderr.
• zero exec --worktree correctly switches the workspace before config/tool/provider setup and rejects the conflicting --fork / --worktree combination.

internal/cli/workflows.go (1)

255-272: 💤 Low value

Reconsider redacting non-sensitive fields.

The function redacts timestamps (StartedAt, EndedAt), check identifiers (ID, Name), and command arguments. Timestamps are typically just ISO8601 strings and check IDs/names are usually simple identifiers like "go.test", not sensitive data. Redacting these may obscure useful diagnostic information without security benefit.

Consider limiting redaction to fields that can contain secrets or sensitive data (Stdout, Stderr, Error) and only redacting Root if path redaction is truly needed.

redaction.RedactString(value, redaction.Options{}) which only redacts secrets,
so filesystem paths (e.g., Path, RepoRoot, report.Root) remain unredacted;
change this by adding path-redaction support in the redaction package (e.g.,
extend redaction.Options with a boolean/array like ObfuscatePaths or
PathsToRedact and implement a helper that normalizes and replaces filesystem
paths with a stable token such as "<REDACTED_PATH>"), then update
redactCLIString to either pass the new option to redaction.RedactString or call
the new RedactPaths helper after/before the existing secret redaction; add unit
tests in the redaction package to cover typical path cases (absolute, relative,
repo roots) and update any callers relying on redactCLIString to ensure CLI
fields (Path, RepoRoot, report.Root) are covered.

[gnanam1990]

@Vasanthdev2004 requested-change blocker is fixed on latest head 0f1e35f.

What changed:

• zero verify now emits redacted copies for text and JSON output, including report.Root.
• zero worktrees prepare now emits redacted copies for text and JSON output, including path and repoRoot.
• Added regressions covering secret-looking path segments for both commands and both output modes.
• Kept normal filesystem paths visible because these commands intentionally report useful locations; only secret-looking tokens embedded in those paths are redacted through the central redaction path.

Validation rerun:

• go test -count=1 ./internal/cli ./internal/worktrees ./internal/verify
• go test -count=1 -p 1 ./...
• npx --yes bun run typecheck
• npx --yes bun test ./tests --timeout 15000
• npx --yes bun run build
• npx --yes bun run smoke:build
• npx --yes bun run smoke:go
• binary smoke proving secret-looking path segments are redacted in verify and worktrees prepare text/JSON output

Current GitHub checks are green.
