Build one plugin per Jellyfin generation (10.9, 10.11, 12)

The single net8.0 build compiled against Jellyfin 10.9.11 still loads on
10.11 and 12, so channels and browsing keep working, but 10.11 changed
APIs in ways that only fail at runtime. A binary audit of the DLL against
the real server assemblies found 9 broken references on both 10.11 and
12 (none on 10.9/10.10):

- TaskTriggerInfo.Type became an enum. GetDefaultTriggers throws, so
  Jellyfin silently gives every SRF task a 24h fallback trigger. The
  recording scheduler therefore ran about once a day and scheduled
  recordings never started.
- ILibraryManager.GetItemList changed its return type: the expiration
  check crashed on every run.
- Jellyfin.Data.Entities.User moved (IUserManager.Users, GetUserData,
  SaveUserData, PlaybackProgressEventArgs.Users): resume cleanup returned
  500 and the playback-stop guard threw on every stop.

Jellyfin 12 also rejects the legacy X-Emby-Token header with an empty
401, which the recordings UI surfaced as "Unexpected end of JSON input".
The pages now send Authorization: MediaBrowser Token="...", verified on
10.9, 10.11 and 12.

The plugin now multi-targets net8.0/net9.0/net10.0 against Jellyfin
10.9.11/10.11.0/12.0.0 (the oldest package of each line, so each DLL
loads on every patch release of it), with JELLYFIN_10_11_OR_GREATER and
JELLYFIN_12_OR_GREATER for the differences. Trigger construction moves
into Utilities/TaskTriggers so the version switch lives in one place.

.gitea/scripts/build-plugins.sh builds one zip per generation. jprm has
no targetAbi flag, so it rewrites build.yaml per flavour and restores
it. Jellyfin installs the highest version whose targetAbi it satisfies,
so the flavour code goes into the last version segment:

  release v1.2.0 -> 1.2.0.9 / 1.2.0.11 / 1.2.0.12
  nightly        -> 1.0.<date>.<run>09 / 11 / 12

The PR, nightly and release workflows use the script and publish one
manifest entry per zip. Verified end to end against a three-entry
manifest: 10.11 installs the .11 build, 12.1 installs the .12 build.
The existing .NET 10 builder image builds all three unchanged.

Supporting changes: the test project multi-targets too, because jprm
publishes the whole solution for one framework at a time, and it drops
its Microsoft.Extensions.Logging 8.0.1 pin, which is a NU1605 downgrade
under the newer Jellyfin packages. CA1873 (new in the .NET 10 analyzers)
is silenced beside CA1848. The release manifest step checks out
origin/master like the nightly does since 7e1973a.

+# Build one plugin zip per Jellyfin generation into ./artifacts.
+#
+# Jellyfin binds a plugin to the exact API it was compiled against, and 10.11 changed
+# signatures that still compile but fail at runtime. So each generation gets its own DLL
+# (see the TargetFrameworks comment in Jellyfin.Plugin.SRFPlay.csproj) and its own
+# manifest entry. Jellyfin installs the highest version whose targetAbi is <= the server
+# version, so the flavour code is folded into the version to keep them apart:
+#
+#   net8.0  -> targetAbi 10.9.0.0   (Jellyfin 10.9 / 10.10)   code 9
+#   net9.0  -> targetAbi 10.11.0.0  (Jellyfin 10.11)          code 11
+#   net10.0 -> targetAbi 12.0.0.0   (Jellyfin 12)             code 12
+#
+# Usage: build-plugins.sh <version-format>
+#   <version-format> is a printf format that receives the flavour code, e.g.
+#     "1.2.0.%d"             -> 1.2.0.9, 1.2.0.11, 1.2.0.12         (release)
+#     "1.0.20260924.204%02d" -> 1.0.20260924.20409, ...20411, ...20412 (nightly)
