fix(coding-agent): resolved symlinked paths before passing to brush

- Resolved symlinked paths before passing to brush shell to keep `pwd` output aligned with canonical Git worktree paths.
- Added `resolveShellCwd` helper that safely resolves symlinks and falls back to original path on error.
- Added test case verifying symlinked directories are canonicalized before execution.
