The user guide and release notes document TDM and edge intelligence
provisioning flags but provision.py only accepted --ssid, --password,
--target-ip, --target-port, and --node-id.
Add all NVS keys the firmware actually reads:
- --tdm-slot / --tdm-total: TDM mesh slot assignment
- --edge-tier: edge processing tier (0=off, 1=stats, 2=vitals)
- --pres-thresh, --fall-thresh: detection thresholds
- --vital-win, --vital-int: vitals timing parameters
- --subk-count: top-K subcarrier selection
Also validates that --tdm-slot and --tdm-total are specified together
and that slot < total.
Closes#130
