feat: Implement SSH client with authentication support (Task 5)

Browse Source 
- Add SSH client with Connect/Execute/Close/IsConnected
- Implement password, key, and both authentication methods
- Support default key discovery (~/.ssh/id_ed25519, id_rsa, etc.)
- Support passphrase-protected keys via ParsePrivateKeyWithPassphrase
- Path expansion for ~ in KeyID
- Integrate with HandleSSHError for user-friendly errors
- All 4 SSH tests passing + 5 error tests still passing (9 total)

Progress: Tasks 1-5 complete (~40%)
