fix: storage workers and CodeBuddy teardown on Windows after #5720

[lidge-jun]

Summary

ci.yml lane=all on dev 0996ecb59b (run 35942446434) failed five Windows shards.

• windows 1, 2, 7, 8/9: storage workers crashed. fix: close four regressions from the 260923 bundle round #5720 declared the Codex-state list in src/codex/home.ts as a module-level const below defaultCodexHome. The storage workers reach defaultCodexHome during module initialisation through an import cycle; with a ~/.codex directory present (every Windows runner, and most user machines) the call read the const inside its temporal dead zone: ReferenceError: Cannot access 'LOCAL_CODEX_STATE' before initialization in the trash-restore and policy-run workers. The list is now local to the function. Linux shards passed only because their sandbox home has no ~/.codex, so the check short-circuited first.
• windows 3/9: CodeBuddy compiled-MCP teardown. afterEach removed its temp directory with rmSync while Windows still held the compiled ocx executable open (EBUSY). It now uses the shared removeTreeWithRetry helper like other fixture teardowns.

Verification

• bun test tests/codex-integration/codex-home-wsl.test.ts tests/codex-integration/codex-home-wsl-local-state.test.ts tests/storage: 170 pass / 0 fail; bun test tests/providers/codebuddy-mcp-server.test.ts: 5 pass; bun x tsc --noEmit clean.
• Proof is a fresh ci.yml lane=all on the merged dev tip, per the owner's instruction to verify on dev after merging.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.
