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

+DIY 48V LiFePO4 battery storage system (5-20 kWh) with Victron integration for the Wrightstown property. Components: EVE C40 cells, JK BMS, Victron MultiPlus II inverter/charger.
+
+## What Was Done
+
+- System design: 48V LiFePO4, EVE C40 cells, JK BMS, Victron MultiPlus II
+- Capacity range defined: 5-20 kWh depending on cell count
+- Victron integration planned
+- No hardware procured yet
+
+## If Resuming
+
+- Begin with hardware procurement (EVE C40 cells, JK BMS, Victron MultiPlus II)
+- Cell arrival: capacity test each cell individually before assembly
+- BMS configuration: program JK BMS for 48V LiFePO4 pack parameters
+- Victron setup: MultiPlus II commissioning, VE.Configure/VictronConnect
+- Check `projects/wrightstown-solar/docs/` and `session-logs/` for any notes
