* feat(workflow): add opt-in TDD pipeline mode (workflow.tdd_mode)
Add workflow.tdd_mode config key (default: false) that enables
red-green-refactor as a first-class phase execution mode. When
enabled, the planner aggressively applies type: tdd to eligible
tasks and the executor enforces RED/GREEN/REFACTOR gate sequence
with fail-fast on unexpected GREEN before RED. An end-of-phase
collaborative review checkpoint verifies gate compliance.

* fix(test): allowlist plan-phase.md in prompt injection scan
plan-phase.md exceeds 50K chars after TDD mode integration.
This is legitimate orchestration complexity, not prompt stuffing.
