Terminal file viewer/editor + per-window app-command lockdown (#60)

Clicking a file path in Claude's terminal output now opens the file in its own window with a CodeMirror 6 editor. The editor highlights the target line, live-reloads while the file changes, and saves explicitly with hash-based conflict detection. The viewer commands are gated by window label. Every app command is now ACL-gated per window through a Tauri AppManifest. build.rs checks the handler list against the capability files and fails the build on any mismatch.

+  "description": "The terminal file viewer windows (`file-viewer-<n>`, opened by `open_file_viewer` on the app's own `viewer.html`). Same rules as `default.json`, including the layout checks: this file itself must stay a top-level `capabilities/*.json` with no `webviews` or `remote` key, or `build.rs` refuses the build rather than grant something the census cannot see. The five bare `allow-viewer-*` grants are the only app commands a viewer window can invoke: `build.rs` declares the AppManifest that makes tauri enforce that, and refuses any other bare grant in this file. The label gate inside `commands/file_viewer_commands.rs` is still what stops window A acting on window B's registry entry, because the ACL only decides which window may call. The rest of this file is the plugin-command surface a compromised viewer webview could reach, and it is the smallest one that lets the window work. `core:event:allow-listen`/`allow-unlisten` are for `file-viewer-goto` (Rust → this window; the viewer subscribes through `getCurrentWindow().listen`, because a bare `listen()` in *any* window receives an `emit_to`). `core:window:allow-destroy` is not optional: `getCurrentWindow().onCloseRequested` in @tauri-apps/api 2.11 makes Rust `prevent_close()` whenever a JS listener exists and then calls `destroy()` itself, so without this grant the window's X button does nothing once the unsaved-changes guard is installed. `allow-close` is deliberately absent — nothing calls it, and `destroy` is the only exit. No `set-title`/`set-focus`/`unminimize`: those are done from Rust when a second click targets an already-open file. `core:webview:allow-internal-toggle-devtools` is the same dev-only convenience `default.json` carries.",
