Subject: [PATCH] fix: RDP panic logging + CWD starts at home directory

RDP: wrapped connection thread in catch_unwind so panics are logged
to wraith.log instead of silently killing the channel. Error message
now directs user to check the log.

CWD: changed cd . to cd ~ after OSC 7 hook injection so SFTP starts
at the user's home directory on macOS (where / requires explicit nav).
