fix(worktree): symlink node_modules to worktrees for TypeScript support (#1148)

* fix(worktree): symlink node_modules to worktrees for TypeScript support

- Add symlink_node_modules_to_worktree() to Python backend for task worktrees
- Add symlinkNodeModulesToWorktree() to frontend for terminal worktrees
- Use Windows junctions (mklink /J) to avoid admin rights requirement
- Update pre-commit hook to detect worktrees and skip checks gracefully
- Symlinks both root node_modules and apps/frontend/node_modules

Resolves @lydell/node-pty TypeScript errors in git worktrees caused by
missing dependencies. Worktrees now share the main project's node_modules
via symlinks (or junctions on Windows).

* fix: address PR review feedback for symlink implementation

- Add broken symlink detection in Python using is_symlink() check
- Add user-visible warning via print_status when symlink creation fails
- Add console.warn in TypeScript for symlink failures
- Simplify pre-commit hook conditionals (-d follows symlinks automatically)

* style: fix ruff formatting issues

* fix: address PR review findings for terminal worktree and Claude integration

- Use relative symlinks on Unix for portability (matches Python implementation)
- Remove UUOC in pre-commit hook (sed directly instead of cat | sed)
- Fix test mock default title to 'Terminal 1' to match production behavior
- Export shouldAutoRenameTerminal for direct testing with edge case coverage

* fix(tests): add missing mocks for cli-tool-manager to prevent Windows timeouts

The agent-process.test.ts and ipc-handlers.test.ts files were timing out
on Windows because cli-tool-manager was not mocked, causing real file
system and subprocess operations during tool detection.

Added mocks for:
- cli-tool-manager (getToolInfo, getToolPath, deriveGitBashPath, clearCache)
- env-utils (getAugmentedEnv)

* fix(tests): add missing configureTools mock to ipc-handlers.test.ts

The settings handlers use configureTools from cli-tool-manager,
which was missing from the mock causing test failures on all platforms.

* fix: improve dependency detection and add documentation for node_modules paths

- Changed pre-commit hook to check for @lydell/node-pty instead of just
  @lydell namespace for more precise dependency detection
- Added comprehensive documentation explaining why node_modules paths are
  hardcoded and how to extend them in both TypeScript and Python implementations
- Cross-referenced between TypeScript, Python, and pre-commit hook files
  to ensure maintainability

Addresses PR review findings: NEW-002, NEW-003
