fix: resolve custom module.yaml from installed location during manifest generation

- resolveInstalledModuleYaml now checks _bmad/<module>/module.yaml first
  so freshly-installed custom/community modules are found immediately
- manifest-generator passes bmadDir to resolveInstalledModuleYaml for lookup
- removes 'could not locate module.yaml' warnings during custom module install
- allows agents declared in custom module.yaml to be registered in config.toml
