fix: sync spike/sketch workflows with upstream skill improvements
Spike workflow:
- Add prior spike check — skips already-validated questions
- Add comparison spikes (NNN-a/NNN-b) for head-to-head evaluation
- Add research-before-building step (context7 + web search)
- Add forensic logging/observability for runtime-interactive spikes
- Add Type column to MANIFEST, type/Research/Observability to README
Sketch workflow:
- Add research-the-target-stack step — check component availability,
framework constraints, and idiomatic patterns before building
Spike wrap-up workflow:
- Replace per-spike curation with auto-include-all (every spike carries
signal: VALIDATED=patterns, PARTIAL=constraints, INVALIDATED=landmines)
- Add Step 10 intelligent routing — integration spike candidates,
frontier spike candidates, and standard next-step options
Commands updated with context7/WebSearch tools and --text flag.
