chore(upstream): sync marcode through ca72e381c

[maarco]

Merges pingdotgg/t3code@ca72e381c into Marcode. 63 upstream commits, merge base e6987965, 33 conflicts resolved by hand.

Supersedes the blocked-sync tracking issues #1, #3 and #4 — all three name upstream shas that are ancestors of ca72e381c.

Hotspot decisions

path	decision
apps/web/src/components/ThreadTerminalDrawer.tsx	Upstream replaced xterm with a Ghostty surface. Marcode keeps its xterm drawer; apps/web/src/terminal/ghostty/** lands unused as the migration path. Deferred, not discarded.
apps/web/src/components/files/**	Right-panel file surface stays retired. Upstream's new ProjectFilePicker and ProjectContentSearchDialog open files through the floating editor instead.
apps/web/src/components/Sidebar.tsx	Marcode's chrome kept (floating nav owns settings); upstream's SidebarSeparator removal carried over since its import is gone.
apps/web/src/components/ProjectScriptsControl.tsx	Marcode's pill controls kept; upstream's compact control width ported onto the surviving Tooltip buttons.
apps/web/src/components/CommandPalette.tsx	Upstream replaced toggleOpen with toggleMode(mode); the floating pill nav listener follows it.
apps/server/src/persistence/Migrations.ts	Marcode keeps id 33 (ProjectWorkspaceLayout). Upstream's ProjectionThreadTitleRegeneration shifts to 36 so applied installs never renumber.
apps/server/src/cli/**, apps/server/src/cloud/**	Upstream behavior taken (serveCommand, systemctl --no-block); Marcode service identity (marcode.service) and copy kept.
apps/mobile/**	CompactBrandTitle uses MarcodeMark; showcase targets the production variant with Marcode's scheme and package id.
docs/**	Upstream's architecture/ + reference/ → internals/ restructure adopted; Marcode branding and Marcode-only pages kept in the index.
.github/workflows/ci.yml	Marcode's macos-26 runner kept rather than upstream's Blacksmith runners.

Coupled changes

effect-version-subtree reported blocking, but pnpm-workspace.yaml moved only Clerk versions — effect stayed at 4.0.0-beta.102, so .repos/effect-smol is still in sync. No subtree sync needed.

pnpm-lock.yaml was regenerated with pnpm 11.10.0, not hand-merged.

Verification

• Full workspace typecheck clean, 15 packages.
• Lint clean, exit 0, zero errors.
• apps/web: 209 test files, 1986 tests pass.
• Focused server (persistence, cloud, cli), scripts and oxlint-plugin-marcode suites pass.
• vp fmt --check clean on every hand-edited file.

Follow-up

The Ghostty terminal migration is deliberately deferred. apps/web/src/terminal/ghostty/** is in the tree with its own passing tests but nothing imports it yet.
