0.10.0

Added

• Three repository-operation skills for agents under .agents/skills/
  (mirrored to .claude/skills/): nddev-repo-orientation (instant mental
  model, file map, contract index, and a task router), nddev-change-flow (the
  complete golden-path checklist, including paired-variant mirroring and the
  runtime-coverage "static-only dance"), and nddev-release-flow (version prep,
  the signed tag, the immutable-release verification checklist, and the
  post-release ledger re-promotion). They complement the eight portable
  CI/GitHub-Actions doctrine skills and route to the catalog and agent
  instructions as the source of truth rather than duplicating volatile facts.
  EXPECTED_SKILLS and the AGENTS.md / .claude/CLAUDE.md skill sections now
  describe the two groups.

Changed

• Re-promote the release-supply-chain.yml runtime-coverage record to
  runtime-proven after the 0.9.0 release run
  (…/actions/runs/29173277373 at e27d4e3) re-executed the current workflow
  live, recording the fresh run URL and proven_digest. Completes the honesty
  cycle opened when RVR-P2-011 edited the workflow and correctly dropped it to
  static-only.
