adlee-was-taken fb1f28161c feat(wasm): secure device API (private keys never cross to JS) ...

- register_device() generates signing + deploy keypairs via core device
  module, stores them in DEVICE_STATE (once_cell Lazy<Mutex>), and
  returns only public keys to JS
- sign_for_git() signs data using the internal signing key
- get_device_info() returns name and public keys; returns null if not
  registered
- clear_device() zeroes and drops device state (logout / re-registration)
- Removed generate_device_keypair() which exposed raw private key bytes

Fixes audit I5: private key material no longer crosses the WASM boundary.
