Run Tesla's open-source vehicle-command proxy so a fleet backend can send signed vehicle commands without the private key leaving local infrastructure

Steps
Build the teslamotors/vehicle-command Go repo's tools via 'go install ./...', or pull the tesla/vehicle-command Docker image
Generate a command-authentication key pair with the tesla-keygen tool
Register the domain and public key with Tesla via the partner-endpoints /register call, then complete owner enrollment through https://tesla.com/_ak/<your_domain>
Launch tesla-http-proxy with a mandatory TLS cert/key and the private key file, exposing a local REST endpoint (e.g. https://localhost:4443/api/1/vehicles/$VIN/command/<cmd>)
Point backend services at the local proxy (with an OAuth bearer token in the Authorization header) instead of holding or transmitting the signing key directly, using tesla-control for ad hoc BLE/internet command testing
Known gotchas
The proxy has no non-TLS option — a valid TLS cert/key pair is required to even start tesla-http-proxy, which trips up quick local testing setups
Pre-2021 Model S/X vehicles don't support the new signed-command protocol at all and must go through the older Owner API/Fleet API path instead
Only the OAuth token travels to Tesla's servers through this setup — the private signing key must stay local to the proxy host, so deploying the proxy on a shared or less-trusted server defeats its security model
