Add QA lifecycle gap closures: 6 new skills + 2 updated (56→62 skills)

New skills:
- /bug-triage: severity/priority classification, sprint assignment, trend analysis
- /regression-suite: GDD critical path coverage map + fixed-bug regression test audit
- /test-evidence-review: quality review of tests and manual evidence (assertions, edge cases, sign-offs)
- /test-helpers: engine-specific helper library generation (Godot/Unity/Unreal)
- /soak-test: extended play session protocol with timed checkpoints and memory monitoring
- /test-flakiness: CI log analysis, flaky test detection, quarantine recommendations

Updated skills:
- /smoke-check: added --platform pc|console|mobile|all argument with platform-specific checks
- /architecture-review: added rtm mode with Phase 3b story+test linkage and RTM output file

 description: "Run the critical path smoke test gate before QA hand-off. Executes the automated test suite, verifies core functionality, and produces a PASS/FAIL report. Run after a sprint's stories are implemented and before manual QA begins. A failed smoke check means the build is not ready for QA."

+## Parse Arguments
+
+Arguments can be combined: `/smoke-check sprint --platform console`
+
+**Base mode** (first argument, default: `sprint`):
+- `sprint` — full smoke check against the current sprint's stories
+- `quick` — skip coverage scan (Phase 3) and Batch 3; use for rapid re-checks
+
+**Platform flag** (`--platform`, default: none):
+- `--platform pc` — add PC-specific checks (keyboard, mouse, windowed mode)
+- `--platform console` — add console-specific checks (gamepad, TV safe zones,
+  platform certification requirements)
+- `--platform mobile` — add mobile-specific checks (touch, portrait/landscape,
+  battery/thermal behaviour)
+- `--platform all` — add all platform variants; output per-platform verdict table
+
+If `--platform` is provided, Phase 4 adds platform-specific batches and
+Phase 5 outputs a per-platform verdict table in addition to the overall verdict.
