plan2code-bot: replace auto-responder with LLM-as-judge evaluation

Bot now acts as an authentic QA agent instead of rubber-stamping every
question and step.

- intelligent-responder answers AskUserQuestion via LLM using current
  observations (tools used, files created, errors) instead of keyword
  matching; auto-responder removed.
- evaluator runs after each step with step-specific criteria
  (prompts/evaluation-criteria.ts), produces 0-100 score plus
  strengths/weaknesses/critical issues. Avg <60 blocks finalization.
- observation-collector captures tool_use, file writes, errors, and
  question reasoning; session-runner falls back to scraping tool_use
  blocks when canUseTool doesn't fire and dedupes both sources.
- Bot writes BOT-EVALUATION.md and BOT-NOTES.md for metrics analysis.
- Idea generator: 12 categories instead of CLI/web-app coin flip,
  stronger seed adherence, less developer-tool bias.
- Init step now writes a minimal AGENTS.md stub instead of running
  the full init skill, avoiding hallucinated architecture before plan.
- Implement step uses Read/Write/Edit/Glob/Grep directly instead of
  a Skill sub-session that produced no visible tool observations.
- bin: add --help, accept --idea="value" form, strip surrounding
  quotes; evaluator maxTurns 3 -> 30; warn when parser misses SCORE.
