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.

+# Changelog
+
+All notable changes to scrum4me-mcp.
+
+## [0.6.0] — 2026-05-04
+
+Adds support for Scrum4Me M12 (Idea entity + Grill/Plan jobs).
+
+### Added
+
+- **`get_idea_context(idea_id)`** — fetch full idea + product + recent logs + open questions for agent context.
+- **`update_idea_grill_md(idea_id, markdown)`** — save grill-result + transition to GRILLED + IdeaLog{GRILL_RESULT}.
+- **`update_idea_plan_md(idea_id, markdown)`** — save plan with server-side yaml-frontmatter validation; ok → PLAN_READY, parse-fail → PLAN_FAILED + IdeaLog{JOB_EVENT, errors}.
+- **`log_idea_decision(idea_id, type, content, metadata?)`** — DECISION/NOTE entries on the idea timeline.
+
+### Changed
+
+- **`ask_user_question`** — now accepts exact one of `story_id` OR `idea_id` (zod xor refine). Idea-questions are user-private (owner-scoped, no productAccessFilter).
+- **`wait_for_job`** — response now includes `kind: 'TASK_IMPLEMENTATION' | 'IDEA_GRILL' | 'IDEA_MAKE_PLAN'`. For idea-jobs the payload returns `idea`, `product`, `repo_url`, `prompt_text` (embedded prompt from `src/prompts/idea/`) and **no worktree** (agent works in user's existing repo).
+- **`update_job_status`** — for `failed` on `IDEA_GRILL` / `IDEA_MAKE_PLAN`: idea status auto-transitions to `GRILL_FAILED` / `PLAN_FAILED` + IdeaLog{JOB_EVENT}. Auto-PR + worktree-cleanup skipped for idea-jobs.
+- **Health version** — now read dynamically from `package.json` at module load (was hardcoded; resolved sync-issues at deploy time).
+
+### Schema
+
+- Vendored `prisma/schema.prisma` synced with Scrum4Me M12 (Idea + IdeaLog models, IdeaStatus + ClaudeJobKind + IdeaLogType enums, ClaudeJob.task_id nullable + idea_id + kind, ClaudeQuestion.story_id nullable + idea_id, check-constraints, pg_notify-trigger update).
+- Pinned to scrum4me commit on branch `feat/m12-ideas` until merged to main.
+
+### Migration notes
+
+- Requires Scrum4Me database to have M12 migration applied (`20260504172747_add_ideas_and_grill_jobs`).
+- Worker runtime: see `vendor/scrum4me/docs/runbooks/mcp-integration.md` — batch-loop now switches on `kind` discriminator.
