5.0.0-JF12-beta

Jellyfin 12.0 (.NET 10) beta 5.0.0-JF12-beta (plugin version 5.0.0.25).
Install via the beta repository URL (a Jellyfin 12.0 server picks this build automatically by targetAbi):
https://raw.githubusercontent.com/iderex/jellyfin-plugin-sso/manifest-beta/manifest.json

Scope note (#743): the JF12/5.0 line is not validated against a live Jellyfin 12.0 server yet — no 12.0 GA server exists to run the E2E checklist against. It is CI-built and unit/conformance-tested only, and it is NOT part of the 4.x (Jellyfin 10.11) release-candidate gate; the 5.0 line clears its own live-validation gate when a Jellyfin 12.0 RC/GA build is available. Use these betas for testing, not production.

What's Changed

• Fail the publish when a Jellyfin generation drops out of the manifest by @iderex in #946
• Generate the plugin manifest in-house: paginated, checksum-paired, per-ABI capped by @iderex in #947
• Skip blank configured role entries in all allow-list matching by @iderex in #953
• Publish both betas from main; retire the stable channel until first stable by @iderex in #955
