This fixes a critical security issue where path parameters from client requests
were not validated against ALLOWED_ROOT_DIRECTORY, allowing attackers to access
files and directories outside the configured root directory.
Changes:
- Add validatePath() checks to 29 route handlers that accept path parameters
- Validate paths in agent routes (workingDirectory, imagePaths)
- Validate paths in feature routes (projectPath)
- Validate paths in worktree routes (projectPath, worktreePath)
- Validate paths in git routes (projectPath, filePath)
- Validate paths in auto-mode routes (projectPath, worktreePath)
- Validate paths in settings/suggestions routes (projectPath)
- Return 403 Forbidden for paths outside ALLOWED_ROOT_DIRECTORY
- Maintain backward compatibility (unrestricted when env var not set)
Security Impact:
- Prevents directory traversal attacks
- Prevents unauthorized file access
- Prevents arbitrary code execution via unvalidated paths
All validation follows the existing pattern in fs routes and session creation,
using the validatePath() function from lib/security.ts which checks against
both ALLOWED_ROOT_DIRECTORY and DATA_DIR (appData).
Tests: All 653 unit tests passing

This commit consolidates directory security from two environment variables
(WORKSPACE_DIR, ALLOWED_PROJECT_DIRS) into a single ALLOWED_ROOT_DIRECTORY variable
while maintaining backward compatibility.
Changes:
- Re-enabled path validation in security.ts (was previously disabled)
- Implemented isPathAllowed() to check ALLOWED_ROOT_DIRECTORY with DATA_DIR exception
- Added backward compatibility for legacy ALLOWED_PROJECT_DIRS and WORKSPACE_DIR
- Implemented path traversal protection via isPathWithinDirectory() helper
- Added PathNotAllowedError custom exception for security violations
- Updated all FS route endpoints to validate paths and return 403 on violation
- Updated template clone endpoint to validate project paths
- Updated workspace config endpoints to use ALLOWED_ROOT_DIRECTORY
- Fixed stat() response property access bug in project-init.ts
- Updated security tests to expect actual validation behavior
Security improvements:
- Path validation now enforced at all layers (routes, project init, agent services)
- appData directory (DATA_DIR) always allowed for settings/credentials
- Backward compatible with existing ALLOWED_PROJECT_DIRS/WORKSPACE_DIR configurations
- Protection against path traversal attacks

- Added docker-compose.override.yml to .gitignore to prevent it from being tracked.
- Introduced a new example configuration file for docker-compose.override.yml to guide users in setting up their local development environment.
