## Summary
Bundled plugins now persist shared runtime state in project-scoped
PostgreSQL tables instead of maintaining independent SQLite authority.
Reports, CLI Printing Press, Compound Engineering, Roadmap, Even
Realities, and WhatsApp all follow the same ownership and startup
contract as Fusion core.
## Design decisions
- Plugin schema hooks run through the host’s PostgreSQL owner and
enforce project isolation.
- The SDK exposes the host contract needed by bundled plugins without
importing engine internals.
- Legacy Roadmap ownership fixtures use the supported empty-owner
sentinel, preserving current composite primary/foreign keys while
exercising backfill behavior.
- The lockfile travels with the Even Realities PostgreSQL dependency so
packaged installs remain reproducible.
## Validation
- All six affected plugin builds pass.
- Affected plugin suites pass: 773 tests across Printing Press, Compound
Engineering, Even Realities, Reports, Roadmap, and WhatsApp.
- `pnpm test:gate` passes all 478 gate tests.
- This PR changes 40 files.
## Stack
- Depends on #2110 → #2109 → #2108.
- The documentation/release PR completes the stack.

## Summary by CodeRabbit
* **Breaking Changes**
* PostgreSQL is now required for runtime storage; SQLite files are used
only as one-time migration inputs.
* The legacy `FUSION_NO_EMBEDDED_PG` fallback has been removed.
* **New Features**
* Added project-isolated PostgreSQL storage for plugins, reports, tasks,
notifications, and other plugin data.
* Added agent tools for reports and CLI service drafts.
* Added PostgreSQL schema initialization support for plugin authors.
* **Bug Fixes**
* Improved migration and recovery of legacy plugin state.
* Prevented cross-project data access and strengthened transactional
schema updates.
* **Documentation**
* Updated storage, migration, deployment, plugin authoring, CLI, and
dashboard guidance for PostgreSQL.

Added memoization for startup slim task list reads (`store.ts`), with dashboard server routing startup reads through the memo window and tests covering the store watcher consumers in scheduler and worktree-pool, plus performance documentation.
