Rename the bridge to the forge service; this repository is the add-on

- bridge/ → forge/, module and binary ipcr-forge, image ghcr.io/yundera/ipcr-forge
  (was ipcr-forge-bridge); releases are plain vX.Y.Z tags (workflow image.yml)
- data folders $AppID/bridge/{state,secrets} → $AppID/forge/..., in-container /forge
- docs link to the engine (Yundera/ipcr) instead of relative paths; README
