feat: add github-native coordination (epic-* commands + scripts + tests)
Adds a GitHub-native coordination layer on top of ECC:
Commands (7 new slash commands):
- epic-claim, epic-sync, epic-validate, epic-publish
- epic-review, epic-unblock, epic-decompose
Scripts:
- scripts/github-coordination.js — CLI entry point
- scripts/lib/github-coordination.js — core library (state machine, gh API wrappers)
- scripts/status.js — coordination status reporter
Config:
- config/github-native-coordination.json — labels, review policy, validation gates
Tests:
- tests/lib/github-coordination.test.js — 15 unit tests for pure functions
- tests/scripts/github-coordination.test.js — integration/CLI test suite
Registry:
- docs/COMMAND-REGISTRY.json — adds 7 epic-* entries, totalCommands 84 → 91
No encoding changes, no prp-* modifications, no Windows shims.
