Copilot does not support custom slash commands via `.copilot/commands/` —
that path was a project invention with no official discovery mechanism.
Plugin commands emitted there were invisible to Copilot CLI and VS Code.
Instead, emit each plugin command as a Copilot skill SKILL.md with:
- user-invocable: true (appears in VS Code / menu)
- disable-model-invocation: true (not auto-loaded, only on demand)
- hyphenated name `<plugin>-<command>` per VS Code Agent Skills spec
Legacy `.copilot/commands/` emission retained for backward compat.
Closes the loop on commands-not-working-in-Copilot-CLI investigation.
- CopilotAdapter now writes to ~/.copilot/agents/ and ~/.copilot/skills/
- Updated generate.py to pass ~/.copilot/ as output_root for copilot
- Added copilot stale artifact detection to doc_gardener.py
- Updated validate_generated.py to check ~/.copilot/agents/ (with fallback)
- Removed old copilot gitignore entries and cleaned up stale artifacts
- No install step needed — make generate HARNESS=copilot writes directly
