* fix(plugins): align hook and tool registrations
Reuse gateway-owned plugin registrations for matching hooks and tools while loading only missing tool owners from narrower runtime scopes.\n\nCo-authored-by: w33d <w33d@steadholme.local>
* test(plugins): cover mixed registry tool owners
Verify gateway-pinned and compatible active registrations compose without another plugin load.

* 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

Local extension before_tool_call/after_tool_call hooks registered but
never fired after a scoped mid-run plugin activation (harness or memory
ensure) rebound the global hook runner to a narrow registry, dropping
hooks unique to the broader registry (#91918).
The runner is now created once and resolves hooks live on every dispatch
from the composed set of currently-live registries (the most recently
initialized registry, the active registry, and the pinned channel and
http-route surfaces) instead of freezing one registry. The loader's
one-shot preserve gate is removed since activation order no longer
matters. Per-plugin ownership prefers loaded records so a failed scoped
reload cannot shadow a healthy pinned registration (including a
fail-closed tool-call gate), and the explicitly initialized registry
stays highest precedence so SDK callers keep an authoritative registry.
Reuses the live-registry collector the agent-event bridge already uses
so both dispatch surfaces agree on what is live.
