- Install patched nogui bridge as both /usr/bin/bridge and /usr/bin/proton-bridge
- Give copied binaries explicit target names for clarity

- Run bridge from /usr/bin via new BRIDGE_BIN variable
- Kill both bridge and proton-bridge process names on init
Prevents Proton auto-updates from reverting IMAP/SMTP to loopback-only.
