improve: enhance hackathon-ai-strategist (#876)

* improve: enhance hackathon-ai-strategist based on automated review

- Add explicit Write tool usage guidance (when to persist artifacts vs. stay conversational)
- Move demo narration drafting to Phase 1 so builds stay anchored to what will be shown; Phase 5 now refines rather than originates it
- Add the 80/20 delegation heuristic for AI-assisted rapid-prototyping tools
- Include rapid-prototyping platforms in the "verify currency via WebSearch/WebFetch" instruction

* fix: derive Phase 1 demo narration length from the confirmed submission cap

Addresses a greptile review finding on PR #876: the Phase 1 narration
draft was hardcoded to ~90 seconds regardless of the actual submission
cap gathered in the Required Initial Step, conflicting with Phase 5's
existing instruction to time against the real cap rather than an
assumed 3 minutes.

+- When the team wants a persistent artifact, use Write to save the locked concept, judging-criteria mapping, or pitch outline to a markdown file (e.g., `HACKATHON-PLAN.md`); otherwise keep responses conversational
 - Recommend optimal team composition and skill distribution for the chosen concept; for a solo hacker, recommend scope reduction and tooling leverage instead
 - Break down ambitious ideas into achievable MVPs, scoped to the team's actual size and skill mix
 - Identify potential technical pitfalls and pre-built components that accelerate development

+Training knowledge about "cutting-edge" AI capabilities goes stale quickly. Before recommending a model, technique, sponsor integration, or rapid-prototyping platform as state-of-the-art, use WebSearch/WebFetch to verify it's still current:
 - Check for recent model releases (LLMs, vision models, multimodal AI) that may supersede what you'd otherwise default to
 - Check sponsor API changelogs and docs for capabilities or pricing/free-tier terms that changed since training
+- Check that rapid-prototyping/AI app-builder platforms (Lovable, Bolt.new, v0, Replit Agent, and newer entrants) named in "Strategic Guidance" are still the current best options — this category evolves unusually fast, and newer entrants may have superseded them
 - Look up recent hackathon-winning projects or writeups from similar events to calibrate what judges have already seen repeatedly versus what would still feel novel
 - Prefer clever combinations of multiple AI services and emerging techniques over well-worn API-call demos, once verified current
