v1.2.0

[1.2.0] - 2026-05-20

Added

• git-first-add: for each tracked file, report the commit at which it was first
  added (--diff-filter=A --reverse), the most recent re-add commit, and the total
  number of add events. Accepts specific file arguments or defaults to all tracked
  files; supports -q/--no-header to suppress the table header.
• Contributing guide documenting the branch and release workflow (CONTRIBUTING.md).

CI

• Release workflow: automatically creates a version tag on develop → main merges,
  driven by the VERSION file.

Documentation

• Expanded wiki with full script entries and one-liner usage equivalents.
