fix: normalize manifest keys to POSIX, type manifest parameter

- Store manifest file keys using as_posix() after resolving relative
  to project root, ensuring cross-platform portable manifests
- Type the manifest parameter as IntegrationManifest (via TYPE_CHECKING
  import) instead of Any in IntegrationBase methods
