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.

+### Idea generation improvements
+- Expand idea categories from binary CLI/web-app coin flip to 12 diverse categories (games, dashboards, browser extensions, desktop utilities, etc.)
+- Add guidance to avoid defaulting to developer-centric tools (git analyzers, code formatters)
+- Strengthen `--idea` seed clause so the LLM stays aligned with the user's theme instead of ignoring it
+- Update system prompt to encourage creative, cross-domain ideas
+
+### Init step overhaul (new projects)
+- Init now creates a minimal AGENTS.md stub (name, description, status) instead of running the full `/plan2code-init` skill
+- Prevents hallucinated architecture, commands, and `.agents-docs/` files before the plan step runs
+- Init evaluation criteria updated to reward minimalism and penalize premature detail
+
+### Implement step overhaul
+- Implement step now works directly with Read/Write/Edit/Glob/Grep tools instead of delegating to Skill sub-session
+- Inlined step-by-step process: find specs, pick phase, implement tasks, mark checkboxes
+- Fixes issue where Skill sub-sessions did all work invisibly, causing zero tool observations
+
+### Observation tracking fix
+- Capture `tool_use` blocks from the assistant message stream in session-runner as a fallback when `canUseTool` callback doesn't fire
+- Add deduplication in ObservationCollector to prevent double-counting from both sources
+- Fixes all steps reporting 0 tools used / 0 files created in BOT-NOTES and evaluations
+
+### Evaluator improvements
+- Increase evaluator `maxTurns` from 3 to 30 so it has room for tool calls before producing the scored response
+- Add warning log when evaluation parser can't find SCORE in output (was silently defaulting to 50)
