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.

A new optional inlay-hints-provider export (worlds plugin-inlay-hints / inlay-hints), declared as the inlay-hints provider kind for any language (API 1.3). The host asks the language server and the plugins together for the visible range and returns both in position order; with no server hints the plugins' hints still show. Kinds map to the Inlay Hints settings; labels, tooltips and counts are capped.
