feat: redundant WSL brain serve + keepalive (fail-safe) 

- serve-brain-wsl.sh: serves WSL central brain over HTTP MCP :8090 (independent of Windows brain)
- keepalive-brain-wsl.sh: restarts serve if :8090 drops
- cron agentic-os-brain-keepalive-wsl every 5 min mirrors Windows keepalive
- README documents the two independent :8090 endpoints (WSL + Windows)

- `graphify`'s MCP HTTP serve requires the extra: `pip install "graphifyy[mcp]"` (done in the venv).
- The write path for memory is still `brain/*.md` + `audit` + `data/`; graphify reads those, never writes them.
- Rebuild is scheduled hourly by the `agentic-os-brain-rebuild` cron.
- WSL serve is kept alive every 5 min by the `agentic-os-brain-keepalive-wsl` cron (fail-safe; mirrors Windows `keepalive-brain.bat`).
- Two independent brain endpoints exist on :8090 — WSL (this tree) and Windows (`C:\Users\Austin\Brains\central\`). Either can answer if the other is down.
