v0.18.0 — CapabilityProfileRouting + skill-gate decouple

Highlights

• CapabilityProfileRouting — three-layer model-selection architecture
  (DEC-20260417_1800). Replaces the per-Actor preferences.model pin
  with:
  • Layer A — model catalog (model-recommender skill)
  • Layer B — project/owner preferences (set_config / get_config MCP tools)
  • Layer C — role standard sets: new Role.model_profiles ranked
    array; optional Actor.model_profile_override
  • All 8 permanent team roles populated with Anthropic/OpenAI/Google/
    xAI/DeepSeek fallbacks.
• Skill-gate PreToolUse hook decoupled from session_id — hook now
  scans for any marker with matching contract_hash + 12h TTL. Fixes
  silent lockouts when harness and MCP server disagreed on session id.
• emit_compliance_contract.py echoes hookEventName — required by
  Claude Code 2.1+'s hookSpecificOutput envelope.
• 13 additional /pk-* slash-command promotions — 26 total /pk-*
  commands, 0 legacy processkit commands.

See CHANGELOG.md for the full list.
