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 web view can open a read-only editor tab that streams a process's output, with plugin-defined toggles, Find, wrap, zoom and Clear. The process is authorised in the backend against the exact granted `process:<program>` and its pinned executable, output is bounded, and the stream survives tab switches but ends when the tab closes, the plugin is disabled or the window closes. Adds a web-log test fixture and docs. Verified on macOS; Windows/Linux not run.
