Extract workspace entry indexing into project service

[juliusmarminge]

Summary

• Move workspace entry indexing into a dedicated project service layer.
• Wire workspace cache invalidation through the new service from checkpoint/orchestration flows.
• Extend Git core support for worktree detection, workspace file listing, ignore filtering, and stdin-backed commands.
• Add coverage for workspace indexing, ignore filtering, chunking, and updated Git core behavior.

Testing

• bun fmt
• bun lint
• bun typecheck
• bun run test

Note

Medium Risk
Moderate risk because it refactors workspace search into a new Effect service and extends GitCore.execute semantics (stdin + truncation flags), which can impact git command handling and cache invalidation paths used by the websocket API and checkpoint flows.

Overview
Workspace entry search is refactored into a new Effect service. Adds WorkspaceEntries (search + invalidate) with a cached per-cwd index built either from git (ls-files + check-ignore) or a bounded-concurrency filesystem walk, including query ranking and explicit truncation tracking.

GitCore is extended to support the new indexing flow. execute now supports stdin and returns stdoutTruncated/stderrTruncated; new helpers isInsideWorkTree, listWorkspaceFiles, and chunked filterIgnoredPaths are added, with updated tests.

Runtime wiring and invalidation behavior changes. WorkspaceEntriesLive is added to server/orchestration layers; wsServer uses the service for projects.searchEntries and calls workspaceEntries.invalidate after projects.writeFile, and CheckpointReactor replaces clearWorkspaceIndexCache with service invalidation. Legacy workspaceEntries.ts implementation and tests are removed and replaced with layer/service tests plus a websocket test covering invalidation.

Note

Extract workspace entry indexing into a WorkspaceEntries Effect service

• Introduces a new WorkspaceEntries service (WorkspaceEntries.ts) with search and invalidate methods, replacing the removed global workspaceEntries.ts module.
• The service builds a cached workspace index (15s TTL, 4-key LRU) via git (ls-files + check-ignore) when available, falling back to a concurrency-limited filesystem walk; ignores .git, .convex, node_modules, etc., and caps results at 25,000 entries.
• Adds isInsideWorkTree, listWorkspaceFiles, and filterIgnoredPaths methods to GitCore, with chunked stdin batching for check-ignore (256 KiB max) and NUL-separated output parsing with truncation support.
• CheckpointReactor and wsServer now consume WorkspaceEntries from the Effect environment; projectsWriteFile invalidates the cache after writing so subsequent searches reflect new files.
• Risk: collectOutput in GitCore now returns {text, truncated} instead of a plain string — all callers have been updated, but this is a breaking internal API change.
