fix: resolve all paths relative to script directory for Opus package compatibility

- Add _baseDir/_path() resolution using shell.getRunningProgram() in all
  entry-point scripts (inventoryManager, inventoryClient, craftingTurtle,
  inventoryWebBridge)
- Pass _path function through to manager/config.lua for data/ and config files
- Config files (.manager_config, .inventory_cache, etc.) now resolve relative
  to the package directory rather than CWD
- Exclude startup/ auto-updater scripts from Opus .package manifest
- All dofile() calls now use _path() for portable path resolution
