Phase 3 of RFC #308: Stateful Sense refactor. - Examples (cpu-usage, nerve-health) use initialState + compute(state) - CLI create/init templates generate stateful sense (no SQLite/Drizzle) - Removed: sense query, sense schema commands (no more per-sense SQLite) - Removed: sense-sqlite.ts, schema templates, migration templates - Updated all CLI tests for new sense structure Refs #308, closes #311
