bot-hermes 639306a26f feat: plane-lift schema (states/modules/cycles/links)
Phase 1 of the Plane feature lift into Project E.

Schema changes:
- Add stateGroupEnum, moduleStatusEnum, linkTypeEnum
- Add states table (per-project workflow states with group enum)
- Add modules table (project-scoped planning buckets)
- Add cycles table (time-boxed sprints)
- Add links table (canonical cross-entity mesh)
- Drop taskStatusEnum and tasks.status column
- Add stateId, moduleId, cycleId FKs to tasks
- Drop taskDependencies, noteLinks, noteEntityLinks tables

Project creation bootstrap:
- Seed 5 default states (Backlog/Todo/In Progress/Done/Cancelled) on new project

Minimal API fixes for typecheck:
- Remove references to dropped tables/columns
- Replace status-based queries with completedAt checks
- Stub deprecated dependency/status endpoints for Phase 2

Drizzle migration: 0008_plane-lift-schema.sql (custom, big-bang)
