fix(01-foundation): resolve plan checker blockers — 3 fixes across 01-02, 01-03, 01-04

- 01-02: wave corrected from 1 to 2 (has depends_on: ["01-01"])
- 01-03: middleware rewritten to Edge-compatible fetch pattern; internal API route
  app/api/internal/validate-token/route.ts handles DB query in Node.js runtime;
  tasks/deliverables queries scoped with inArray(); accepted_total null-coalesced
- 01-04: Task 1 and Task 6 merged → 5 tasks total (was 6, exceeded threshold)
- STATE.md: updated to reflect Phase 1 planning verified, ready for execution
