fix(#141): address security-review-bot REQUEST_CHANGES findings
Finding #1 [MAJOR]: replace os.Stat with os.Lstat in checkStaleDocs to
prevent symlink traversal. Symlinks under repoRoot could probe arbitrary
host file existence; Lstat never follows them. Symlinked docs are now
treated as stale.

Finding #2 [MINOR]: resolve --repo-root with filepath.Abs +
filepath.EvalSymlinks before passing to checkStaleDocs, so a symlinked
repo-root cannot bypass the filepath.Rel escape guard.

Finding #3 [NIT]: reject backslashes in ValidateDocPath to prevent
Windows platform edge cases where a path separator may be normalised
differently by the host OS or VCS backend.

Tests added:
- TestCheckStaleDocs_SymlinkOutside: symlink inside repo → outside
- TestCheckStaleDocs_SymlinkInsideRepo: intra-repo symlink also rejected
- TestRunValidateDocmap_SymlinkRepoRoot: symlinked --repo-root resolves OK
- TestValidateDocPath_Backslash: backslash paths rejected
- Backslash cases added to TestValidateDocPath invalid slice

All go test ./... pass, go vet ./... clean.
