v0.5.2

This release replaces v0.5.1, which was tagged but never published — the
release CI jobs failed on Windows because cargo-about rejects shell output
redirection (>) in PowerShell. The tag v0.5.1 exists in git history but has
no corresponding GitHub release or pre-built binaries. v0.5.2 contains all
v0.5.1 changes plus the CI fix.

Improvements (from v0.5.1)

• Release archives now include a THIRD-PARTY-LICENSES.txt file with
  attribution for all third-party dependencies (generated by cargo-about).
• Version update notices now appear even when running --help or --version
  (previously, Cli::parse() called process::exit before print_warning
  could run; now uses try_parse() to regain control).
• README now documents the bugs command, --modules flag, date range flags
  (--date, --days, --from/--to), --proto-signature, and includes
  more usage examples and workflow recipes.

Internal (from v0.5.1)

• Added CHANGELOG.md and wired it into the GitHub release workflow for
  automatic release notes.
• Added license compatibility check to the CLAUDE.md change checklist.

Fixes (v0.5.2)

• Fixed release CI failing on Windows: cargo-about rejects shell output
  redirection (>) in PowerShell; switched to its built-in -o flag.
