fix(macos): prevent PortGuardian from killing Docker Desktop in remote mode (#6755)
PortGuardian.sweep() was killing non-SSH processes holding the gateway
port in remote mode. When the gateway runs in a Docker container,
`com.docker.backend` owns the port-forward, so this could shut down
Docker Desktop entirely.
Changes:
- accept any process on the gateway port in remote mode
- add a defense-in-depth guard to skip kills in remote mode
- update remote-mode port diagnostics/reporting to match
- add regression coverage for Docker and local-mode behavior
- add a changelog entry for the fix
