v1.0.9-beta.002 - fix(metadata): enforce Metron API guidelines and dynamic provider selection
- Added explicit Omnibus/1.0 User-Agent headers to all Metron.Cloud API requests to comply with their strict anti-bot guidelines and prevent server bans.
- Updated the Series Match UI to conditionally render the Metron search provider dropdown only if the admin has configured valid Metron credentials in the system settings.
Closes #83
