0.13.2 — Internal cleanup

0.13.2 — Internal cleanup

This release removes unused and duplicated internal code. Scans, BOMs, policy
evaluation and the CLI do not change.

Highlights

• Unused and duplicated helpers are removed. The unused
  tools.parsers.claude_plugin.parse_at_install_root helper is gone. Endpoint
  scans call walk_plugin_root directly, as before. The BOM linter reuses the
  property map helper in tools.bom. The Skillspector observation source
  reuses the bom-ref helper of the skill posture rule.

Install

uv tool install openaca==0.13.2 or pip install openaca==0.13.2.

Compatibility

Pre-V0 — no back-compatibility hedging.

• tools.parsers.claude_plugin.parse_at_install_root is removed. It was
  an internal helper with no caller. openaca.core does not change.
• openaca:schema_version stays 0.6. The BOM document shape did not
  change.
• The overlay record schema is unchanged.
