Log Message:
SyncTERM: persistent SFTP subsystem channel per SSH session
Open the SFTP subsystem channel once, right after the shell channel
opens, and keep it alive for the lifetime of the SSH session. The
channel's sftpc_state_t, atomics for "SFTP available" and "shell
alive", and the recv thread are all session-scoped; browser / transfer
queue code (later phases) pulls the shared state from sftp_session.h.
add_public_key() stops opening its own channel and just uses the
shared sftp_state. ssh_close() tears down in the right order:
sftpc_finish waits for any in-flight ops to drain, the recv thread
stops polling sftp_chan, then the channel closes, then sftpc_end
releases the state.
If the server doesn't support the SFTP subsystem, sftp_available
stays false and the shell continues normally — this is not an error.
