feat(files): add a setting to show gitignored files

[StiensWout]

The file explorer always hides gitignored files, so users cannot browse build output or other ignored files.

Add Show gitignored files to General settings on web, desktop, and mobile, off by default and saved per client. Settings search finds it by gitignored, .gitignore, ignored files, file explorer, or node_modules. The opt-in server listing includes ignored paths, skips .git and symlink traversal, and caps results at 25,000 entries. Default listings and file/content search keep their existing filtering.

Verified Settings search, opening ignored files, reload persistence, and toggling back in Playwright. Focused service, WebSocket, settings, search, desktop persistence, and mobile preference tests pass. Server and web typechecks pass. Mobile has the same 59 existing navigation/type errors on the base revision; no native simulator pass was run.

Before

Ignored directories are hidden.

After

The setting reveals ignored directories and their files.

Implemented by GPT-6 using Codex in T3 Code.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a user-facing setting across web and mobile and introduces a new server filesystem traversal for ignored files, including timeout and truncation behavior. Its cross-cutting scope and substantial runtime logic warrant human review.

📝 Walkthrough

Walkthrough

The change adds a showGitignoredFiles preference to mobile and web settings. File queries pass includeIgnored to the server, which performs a bounded filesystem traversal for ignored entries. Contracts, error handling, settings UI, search, and tests are updated.

Changes

Gitignored Files Visibility

Layer / File(s)	Summary
Contracts and preference storage packages/contracts/src/project.ts, packages/contracts/src/settings.ts, apps/mobile/src/persistence/mobile-preferences.ts, apps/mobile/src/state/preferences.ts	Contracts define includeIgnored and showGitignoredFiles. Mobile preference storage and state expose the setting.
Ignored workspace traversal apps/server/src/workspace/WorkspaceEntries.ts, apps/server/src/ws.ts, apps/server/src/workspace/WorkspaceEntries.test.ts, apps/server/src/server.test.ts	The server lists ignored entries with a bounded filesystem walk, excludes .git, avoids traversing symlinks, and reports directory-read failures.
Mobile preference and file-tree integration apps/mobile/src/features/settings/SettingsRouteScreen.tsx, apps/mobile/src/features/files/ThreadFilesRouteScreen.tsx, apps/mobile/src/features/files/thread-file-navigator-pane.tsx	Mobile settings add the toggle. Mobile file-tree queries pass the preference as includeIgnored.
Web settings and file-query integration apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts, apps/web/src/components/settings/settingsSearch.test.ts, apps/web/src/components/files/projectFilesQueryState.ts, apps/web/src/components/files/projectFilesQueryState.test.tsx, packages/contracts/src/settings.test.ts, apps/desktop/src/settings/DesktopClientSettings.test.ts	Web settings add the toggle, reset behavior, search entry, and query wiring. Tests cover enabled and disabled states.
