fix(opencode-plugin): track active release branch in CI + align combo-id fixture

The opencode-plugin CI workflow trigger was pinned to release/v3.8.2 since
its creation, so it stopped firing once the active release line moved on —
the workflow never ran mid-cycle. Switch push/pull_request branch filters
to release/** so it tracks whatever release branch is active.

Also align the provider.test.ts fixture expectations with the combo-id
contract from #10345/#10821: mapRawModelToModelV2 leaves bare combo ids
(owned_by: "combo") unprefixed so OpenCode's `-m <plugin>/<combo>` lookup
resolves them directly. The two assertions still expected the old
provider-prefixed form.

Closes #11291
Closes #11292
