* refactor(plugins): keep pinned registry lookup internal
Reuse the existing runtime-state contract so hook and tool ownership does not expand the Plugin SDK surface or treat unpinned active registries as Gateway owners.
* test(plugins): complete hook context fixture
Supply the required tool name in the stateful hook ownership regression context.
* chore: leave contributor release note in PR
Normal contributor PRs do not modify the release-owned changelog; the PR body retains the release note and attribution.
* fix(plugins): align partial registry owners
* fix(plugins): preserve scoped tool diagnostics
