pi-ssh-remote v0.1.8

Added

• Added explicit private-key authentication through ssh -i KEY, including passphrase-protected keys and in-memory passphrase caching for reconnects.

Changed

• Renamed the agent-facing ssh_remote_control tool to the shorter remote name, matching the /remote command.
• Server memory is now keyed by user@host and shared across SSH ports; existing endpoint memories are migrated automatically.
• /remote forget now clears cached private-key passphrases as well as passwords.

Fixed

• None.
