fix: use short config keys in RegisterDef, remove generics helpers

- qq, a2a, bili, files, rss: RegisterDef keys changed from
  namespaced (e.g. "plugin.qq.listen") to short flat keys ("listen")
- a2a, bili: Get() calls updated to match short keys
- rss: replaced readCfg generics with getSetting, added SetAutoRestart(true)
- files: already uses short key Get, only RegisterDef needed fixing
