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 plugin opts a table into click-to-sort by sending it as view body other(kind "table") with its sort; a header click comes back as view-event other(kind "sort", {column, descending}), so no released WIT type changes. The SDK builds and decodes both (Body::sortable_table, ViewEvent::sort). Headers are keyboard-operable, carry aria-sort and show the reported order with an arrow.
