fix(#150): add EvalSymlinks to validateDocmapPath — close dir-symlink bypass
The previous implementation called os.Lstat(absPath) which only avoids
following the *final* path component. A PR committing .review-bot/ as a
directory symlink pointing outside the repo would pass the filepath.Rel
confinement check because the textual path was inside the root while
the resolved destination was not.

Fix: call filepath.EvalSymlinks after filepath.Abs to resolve ALL symlink
components before the confinement check. If EvalSymlinks fails (dangling
symlink, nonexistent target) the path is rejected. The filepath.Rel check
then operates on the fully-resolved path.

Semantic change: file-level in-repo symlinks (target also within root) are
now allowed — the invariant is about where the content lives, not whether
the entry is a symlink. The test TestValidateDocmapPath_Symlink is updated
to test an out-of-repo symlink target, which must still be rejected.

Tests:
- TestValidateDocmapPath_DirSymlinkBypass: reproduces the attack vector
  (dir symlink bypassing textual confinement check) and verifies it is
  now rejected
- TestMainSubprocess_InvalidDocMapPath: subprocess test via validate-docmap
  subcommand — ../../../etc/passwd rejected (closes #146)
- TestMainSubprocess_InvalidDocMapFile: subprocess test — nonexistent file
  rejected (closes #146)
