v1.5.0

Added

• Installer aliases compatible with the common skills CLI interface:
  repeatable --agent/-a, --skill/-s, --copy, -p, -g, and *
  provider selection.
• Explicit copy-only integrity policy and actionable rejection of unsupported
  symlink installs.
• Structured pull request controls with code ownership, a required PR contract,
  Conventional Commits title validation, and release-note enforcement.
• Review-gated release preparation and shipping workflows with semantic-version
  consistency checks, changelog-derived GitHub releases, protected tagging, and
  npm trusted publishing handoff.
• Optional provider-neutral metric, objective, intervention, and connection-state
  contracts with strict schema and referential validation.
• CSV/JSON metric imports, user-owned objective creation and validation, and
  evidence-deduplicated baseline/evaluation reporting with explicit guardrails
  and inconclusive outcomes.

Fixed

• citable install --all now selects every supported provider in addition to
  confirming non-interactively.
• Release preparation now updates and validates the canonical skill version in
  addition to package, lockfile, changelog, and roadmap versions.
