feat(mana-ai): wire shared-ai planner + real mana-llm calls (v0.2)

Service now produces plans end-to-end for due missions. Takes the
shared prompt/parser from @mana/shared-ai, calls mana-llm's
OpenAI-compatible endpoint, parses + validates the response against a
server-side tool allow-list.

- `src/planner/tools.ts` — hardcoded subset of webapp tools where
  policy === 'propose'. Mirror of `DEFAULT_AI_POLICY` in the webapp;
  drift just means the server doesn't suggest newly-added tools
  (graceful degradation). Contract test between the two lists is a
  sensible follow-up.
- `src/cron/tick.ts`
  - Iterates due missions, builds the shared Planner prompt per mission,
    parses the LLM response, logs the resulting plan
  - Per-mission try/catch so one flaky LLM response doesn't abort the
    queue; stats now track `plansProduced` + `parseFailures`
  - `serverMissionToSharedMission()` converts the projection shape to
    the shared-ai Mission type at the boundary
- `resolvedInputs: []` today — the Planner sees concept + objective +
  iteration history only. Full resolvers (notes/kontext/goals via
  Postgres replay) land alongside write-back in the next PR.
- No write-back yet: the plan is logged but not persisted to
  `sync_changes`. Write-back needs an RLS-scoped helper mirroring
  mana-sync's `withUser` pattern — tracked explicitly as the remaining
  open piece in CLAUDE.md.

+ * (`DEFAULT_AI_POLICY` in `data/ai/policy.ts`). This file mirrors the
+ * subset where policy === 'propose' so the mana-ai Bun service can

+ * Drift risk: if the webapp adds a new proposable tool and this file

+ * degradation. A contract test that compares both lists would be a
