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.

Closes#1947
Adds API 1.3 `fs.plugin-dir`: a persistent owner-only directory per plugin (0700 directories / 0600 files on Unix, owner-only ACL on Windows), separate from the packaged code, storage and secrets. The plugin reads and writes under it without fs.* grants, can open files there in the editor and pass their paths to approved programs; editor saves keep the protection, restart keeps the content, uninstall removes it. Traversal and symlink escapes into other plugins' directories are rejected (real-Wasm regressions).
