Add Dependency Trap warning to all gt prime role templates

Temporal language like "Phase 1 blocks Phase 2" triggers incorrect
dependency direction. Added a concise warning to all 6 role templates
(crew, polecat, mayor, witness, refinery, deacon) reminding agents:
- Think "X needs Y", not "X comes before Y"
- Verify with `bd blocked`

+## Dependency Trap
+
+**Temporal language inverts dependencies.** "Phase 1 blocks Phase 2" is backwards.
+- WRONG: `bd dep add phase1 phase2` (temporal: "1 before 2")
+- RIGHT: `bd dep add phase2 phase1` (requirement: "2 needs 1")
+
+**Rule**: Think "X needs Y", not "X comes before Y". Verify with `bd blocked`.
