v4.5.2

Fixed

• styleproof-ci --spec-ref now works from a repo subdirectory. The overlay's
  <rev>:<path> lookups resolved the spec from the repo root, so a workflow
  running the CLI with working-directory: hud and --spec tests/e2e/….spec.ts
  failed with a false "missing at --spec-ref" even though the file exists (hit by
  a consumer's 4.5.1 migration on its first cold capture). The lookups now use git's
  cwd-relative <rev>:./<path> form, matching how the same spec path is used by
  every pathspec call and filesystem write in the overlay.
