Closes#1948
Plugins receive debounced batches of files created, changed and removed outside the editor in open projects, as SDK `Event::FilesChanged` (delivered through `other("files-changed", …)`, so released WIT is unchanged), under the `events` capability and the plugin's path filters. Activation on these events requires API 1.3. Batches are coalesced per plugin through its actor, survive cancellation without losing deltas, and are dropped when the project or host shuts down.

Adds the API 1.3 `endpoints-provider` export and `[[contributes.endpoints]]` (file globs, ^1.3, `project.read`). A plugin's routes join the Spring ones in Search Everywhere, `.http` URL completion and the declaration's Open in HTTP Client gutter action. The UI asks `plugin_endpoints` on demand; the host runs the plugin on a blocking thread, validates the whole list (bounds, project-relative locations, UTF-16 ranges) and caches it per project until a file matching the globs changes, then emits `EndpointsChanged`. A failed or invalid run keeps the last list; disabling, crashing or closing the project withdraws it, and late results can't restore it. Closes#1960.
