Ryan Malloy 1c23c5f2f7 feat: add Web Push Notification support with pull-based retrieval
Adds comprehensive Web Notification API support:
- Intercepts Notification constructor via page.addInitScript()
- Bridges notification data to Node.js via page.exposeFunction()
- Stores notifications in Tab and Context for pull-based retrieval

New MCP tools:
- browser_configure_notifications: grant/deny permissions per origin
- browser_list_notifications: query captured notifications
- browser_handle_notification: click or close notifications
- browser_wait_notification: wait for matching notification
- browser_clear_notifications: clear notification history

Architecture uses modal state pattern for notification handling,
consistent with existing dialog and file chooser patterns.
