Add webview support for Electron apps in native mode (#671)

* Add webview support for Electron apps in native mode

Fixes #580

* Fix cargo fmt violations in actions.rs and browser.rs

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Revert unrelated refactors, keep only webview support changes

- Restore is_none_or (was changed to map_or unnecessarily)
- Restore single-if WebDriver check (was split into nested ifs)
- Restore simple needs_relaunch logic (was expanded into 4 branches)
- Restore find_frame signature (unused selector param was added)
- Restore flat download handler condition (was nested unnecessarily)
- Restore wait_or_kill and graceful close() to preserve cookie flushing

+## Webview Support
+
+Electron `<webview>` elements are automatically discovered and can be controlled like regular pages. When using `--native` mode, webviews appear as separate targets in the tab list with `type: "webview"`:
+
+```bash
+# Connect in native mode
+agent-browser --native connect 9222
+
+# List targets -- webviews appear alongside pages
+agent-browser tab
+# Example output:
+#   0: [page]    Slack - Main Window     https://app.slack.com/
+#   1: [webview] Embedded Content        https://example.com/widget
+
+# Switch to a webview
+agent-browser tab 1
+
+# Interact with the webview normally
+agent-browser snapshot -i
+agent-browser click @e3
+agent-browser screenshot webview.png
+```
+
+**Note:** Webview support requires `--native` mode (raw CDP). The Playwright-based mode does not support webview targets.
