fix(doctor): report macOS keychain signer as present

The keychain signer lacked a HardwareProber, so probeHardware() returned
ok=false and doctor printed "no TEE signer in this build" on macOS — a
false negative, since the signer is registered and private_key_jwt works.
Implement ProbeHardware on keychainSigner (reports backend=keychain,
available when /usr/bin/security is present; no key access, no prompt) so
doctor shows 'keychain TEE available'.
