feat: M12 idea-job support — version 0.6.0

Adds the 4 new MCP-tools for the Scrum4Me M12 Idea-entity flow + extends
3 existing tools to handle the new ClaudeJobKind discriminator.

New tools:
- get_idea_context: full idea + product + open questions + recent logs
- update_idea_grill_md: save grill-result + status → GRILLED + IdeaLog
- update_idea_plan_md: server-side yaml parser validates frontmatter;
  ok → PLAN_READY, fail → PLAN_FAILED + line-info errors
- log_idea_decision: DECISION/NOTE entries on the timeline

Extended tools:
- ask_user_question: xor schema (story_id | idea_id); idea-questions are
  user-private with productId derived from idea.product_id
- wait_for_job: returns \`kind\` discriminator; IDEA_* payloads include
  idea + prompt_text (from src/prompts/idea/) and skip worktree creation
- update_job_status: failed on IDEA_* auto-transitions idea-status to
  GRILL_FAILED / PLAN_FAILED + IdeaLog{JOB_EVENT}; auto-PR + worktree-
  cleanup skipped for idea-jobs

Other changes:
- Health version now read dynamically from package.json (was hardcoded
  '0.1.0' which caused deploy-sync confusion)
- Schema synced to Scrum4Me M12 (Idea + IdeaLog + enums + ClaudeJob/
  Question nullable-FKs + check-constraints + pg_notify-trigger update)
- New @scrum4me-mcp/lib/idea-plan-parser duplicates Scrum4Me's parser
  (drift detected by vendor schema-watchdog)
- Embedded grill+make-plan prompts copied to src/prompts/idea/
- New userOwnsIdea access helper

Tests: 153/153 green; tsc + build clean.

Migration: requires Scrum4Me M12 migration (20260504172747_add_ideas_and_grill_jobs)
applied on the target DB. See vendor/scrum4me/docs/runbooks/mcp-integration.md
for the updated batch-loop with kind-switch.
