* feat(references): add gates taxonomy with 4 canonical gate types
Define pre-flight, revision, escalation, and abort gates as the
canonical validation checkpoint types used across GSD workflows.
Includes a gate matrix mapping each workflow phase to its gate type,
checked artifacts, and failure behavior. Cross-referenced from
plan-phase and execute-phase workflows.
Closes#1715

* fix(agents): move gates.md to required_reading blocks and add stall detection (#1715)
- Move gates.md @-reference from <role> prose into <required_reading> blocks
in gsd-plan-checker.md and gsd-verifier.md so it loads as context
- Add stall-detection to Revision Gate recovery description
- Fix /gsd-next → next for consistent workflow naming in Gate Matrix
- Update tests to verify required_reading placement and stall detection
