chore: add PROJECT_STATE.md to all active projects and clients

Establishes inter-session coordination for 29 projects/clients:
- Full lock/component format for active projects (dataforth-dos,
  radio-show, cascades-tucson, valleywide, instrumental-music-center,
  lens-auto-brokerage, msp-audit-scripts)
- Light format for complete/stalled/planning (msp-pricing, pavon,
  wrightstown-*, gururmm-agent, community-forum, glaztech, etc.)
- Onboarding stubs for recently added clients
