feat(tools): add grep and workspace profile, fix write path

- Add grep_tool: ripgrep with Python fallback; avoid --json with -l/-c.
- Add workspace_profile_tool: scan, languages, tests, packages, git, CI hints; tests.
- write_file: resolve relative paths via workspace root (no data/workspace prefix).
- Update path guard and local public tool tests for new write behavior.
