Dream shipped to prod but its API endpoints weren't in the API reference. Add
the org/project-scoped Dream endpoints (OpenAPI spec + per-endpoint pages + nav):
- GET/PATCH dream/config/ — get / update Synthesis config + plan entitlements
- GET dream/stats/ — lifecycle + synthesis counts
- GET dream/activity/ — supersede/merge feed (keyset-paginated)
- GET dream/runs/ — synthesis runs feed
- GET dream/runs/{run_id}/memories/ — memories within a run
- GET dream/memory/{memory_id}/sources/ — a synthesized memory's sources
- POST dream/preview/ — no-write scope preview
