Switch forgejo-runner to host execution mode

Docker-based runner had networking issues reaching Forgejo from job
containers. Host execution mode runs the runner daemon directly on indri,
with jobs executing on the host. Actions that need Docker use host
networking to access localhost:3001.

- Runner binary compiled locally at ~/code/3rd/forgejo-runner
- Labels use :host suffix instead of :docker://image
- PATH set in launchd plist for mise-managed tools (node, etc.)
- Container network set to "host" for actions needing Docker
