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.

Plugin API 1.3 gains an optional hover-provider export (worlds plugin-hover
and hover): hover(doc, at) returns Markdown and the range it describes. A
plugin declares the hover kind under [[contributes.providers]] for any
language; the host asks it with the language server, under the edit-path
budget, and shows the server's hover first and each plugin's below a rule.
Declaring the kind needs engines.openidea ^1.3. The Rust SDK gains
openidea_plugin::hover and register_plugin!(T, hover); every shipped
component is rebuilt for the WIT change.
