Merge Risk: 🟡 Moderate · up to Plugin teardown can leave stale callbacks active or interfere with resources from a rapid re-registration, so the lifecycle fixes should be completed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 109: Update the lifecycle event table entry for PLUGIN_EVENT_ERROR to
state that it is emitted when either install() or uninstall() fails, keeping the
surrounding documentation unchanged.
In `@library/src/helpers/pluginManager.ts`:
- Line 162: Update the plugin installation lifecycle around uninstall() and
destroy() so the installation is marked inactive before plugin.uninstall(api)
runs; ensure registerComponent(), onSpecLoaded(), and on() reject or ignore
calls made through inactive installations, including after awaited teardown and
after destroy() clears state. Add coverage for an async uninstall hook
attempting to register a component and listener.
In `@library/src/index.ts`:
- Line 12: Restore the pluginId type in the package root export block so
consumers importing it from `@asyncapi/react-component` continue to type-check; do
not remove this public re-export.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy liftSerialize same-name registration with the previous uninstall.
PluginManager.unregister()deletes the current entry and startsrunUninstall(entry)without retaining or awaiting its promise.register()checks only the active and pending maps, so it can install another plugin with the same name before the olduninstall()completes. Becauseuninstall()may be asynchronous and is responsible for releasing resources acquired byinstall(), a teardown that uses shared plugin state can close or mutate a resource created by the new installation.Track the pending uninstall for each plugin name and delay same-name registration until it completes, or isolate resource ownership for each installation.

This PR extends the plugin API with typed, slot-specific context for operation and info plugins. Plugin components now receive the parsed AsyncAPI document and relevant models, improving type safety and removing the need for manual casting.
It also adds an optional uninstall() lifecycle hook and automatic cleanup of plugin-owned listeners and components. Plugins are safely cleaned up when unregistered, removed from props, or when the AsyncAPI component unmounts, including cases where installation is still pending.
Documentation and tests have been updated to cover the new context API and teardown behavior. All focused tests, type checks, lint checks, and diff validation pass.
