feat(brain): add Goal Editor UI and event-driven incremental streaks

Final two TODOs resolved — the Companion Brain backlog is now empty.

Goal Editor (GoalEditor.svelte):
- Modal with event type picker (13 options), count/sum mode,
  optional filter field/value, target value/period/comparison
- Integrated into Goals ListView with "Eigenes" button alongside
  the existing "Vorlage" template picker
- Creates custom goals via goalStore.create()

Incremental Streaks (rewritten streaks.ts):
- Persistent _streakState table replaces the 90-day lookback scan
- 6 streak definitions: water goal, tasks, meals, workout, journal,
  meditation — each triggered by specific domain events
- Event bus subscription marks streaks active on matching events
- markActive() is O(1): read state → check if today already active
  → increment or reset based on consecutive day check
- useStreaks() reads from _streakState (single table scan, no
  per-day queries) instead of 270+ queries worst case
- startStreakTracker/stopStreakTracker wired into layout lifecycle

+ * Streaks — Event-driven consecutive-day tracking.
  *
- * Each streak definition queries a specific module to check if "today
- * counts" (e.g. water goal reached, at least 1 task completed, etc.).
- * The streak engine then looks backwards through the event store to
- * compute the current streak length.
+ * Persistent state in `_streakState` table. Updated incrementally
+ * via event bus subscription instead of scanning 90 days of history.
+ *
+ * On relevant events (DrinkLogged, TaskCompleted, MealLogged, etc.),
+ * the streak for today is marked active. On each read, we check if
+ * the streak is still consecutive or has been broken.
  *
  * Status:
- *   active    — today or yesterday was active
- *   at_risk   — yesterday was NOT active, but the day before was
- *   broken    — more than 1 day gap
+ *   active   — today is active
+ *   at_risk  — today not yet active, but yesterday was
