Fix git status startup spawn failures

[khaliqgant]

Summary

• replace execFile-based git reads with a shared spawn runner that controls stdio explicitly
• catch git:status failures in the IPC handler and return an empty status after a single warning instead of repeatedly rejecting during startup polling
• stop full-diff startup from spawning one git diff --no-index process per untracked file
• compute untracked summary additions in-process with bounded file reads, and skip overlapping renderer git polling requests

Verification

• npm run build on the clean PR branch
• local dirty checkout: npm run build
• local dirty checkout: npm run typecheck
• local dirty checkout startup smoke test with active Pear project: Electron main CPU stayed around 3-4%, no git diff --no-index child flood, and no repeated git:status spawn EBADF handler errors observed

Notes

• npm run typecheck is not defined on current clean main
• npx tsc -b --noEmit on clean main still fails on pre-existing type drift in cloud/proactive/store/index/DiffPane/GraphView/syntax-highlighter files`

📝 Walkthrough

Walkthrough

The pull request refactors Git command execution from execFile to spawn-based runGit, adds custom GitCommandError with stderr/stdout capture, changes untracked addition counting to read file contents directly instead of using git diff, introduces warning deduplication for IPC status failures, and adds concurrent request deduplication in the renderer store.

Changes

Git Operations Reliability and Performance

Layer / File(s)	Summary
Git command execution refactoring src/main/git.ts	GitCommandError class captures exit code, stdout, stderr. runGit helper built on spawn validates working directory, supports optional stdin and custom env, buffers output, enforces 10MB size limit, and provides consistent error semantics. git, gitWithEnv, and gitWithInput refactored to call runGit.
Direct untracked file line counting src/main/git.ts	New countLines and getUntrackedAdditions helpers read up to 500 untracked files (1MB max each), count lines, and sum results with best-effort error handling, replacing previous per-file git diff --no-index approach.
getDiff and getSummary updates src/main/git.ts	getDiff now returns only git diff output without appending generated no-index diffs. getSummary computes untracked additions via direct file reading and adds them to tracked totals.
IPC handler error deduplication src/main/ipc-handlers.ts	Module-level gitStatusWarnings cache with error-to-message conversion and single-warning-per-path:message logging. git:status handler wrapped in try/catch, emits deduplicated warning on failure, returns empty array instead of error propagation.
Renderer store concurrent request deduplication src/renderer/src/stores/git-store.ts	Module-level tracking sets for in-flight status, summary, project status, and diff requests. fetchStatus, fetchSummary, fetchProjectStatus, and fetchDiff early-return if request already in-flight, remove marker in finally, preserve existing state comparison and error fallbacks. selectFile resets diff and loading when file is cleared instead of triggering fetchDiff.

Poem

🐰 A rabbit hops through git commands new,
With spawn instead of exec, a faster view,
Untracked files counted, errors deduped with care,
Concurrent requests blocked, no duplicate air!
Reliability blooms where duplication was—
The warren runs swiftly, no network pause! 🌱
