Dave d1f7ba82f2 feat(#1592): add plan:pre codebase-drift pre-check before planner runs
Add a non-blocking, warn-only codebase-drift gate at plan:pre so a stale
STRUCTURE.md is surfaced before /gsd:plan-phase spawns the planner, instead
of being discovered mid-execution by the existing execute:wave:post gate.
Gated on a dedicated workflow.plan_drift_precheck toggle (default true),
independent of schema_drift_gate. Never blocks planning, never spawns the
mapper agent at plan time.

Review feedback (#1595):
- Use a documented conventional-commit type (feat, not enhance) per
  CONTRIBUTING.md / gsd-validate-commit.sh.
- Normalize the plan_drift_precheck command references to the colon prose
  form (/gsd:plan-phase, /gsd:map-codebase) to match plan-phase.md §5.65;
  registry regenerated from capability.json.
- Make the test temp dirs hermetic: drain mkdtemp dirs in an after() hook
  via the helpers.cleanup() budget (local/no-raw-rmsync-in-tests-compliant).

Closes #1592
