feat(n8n): expand browser-cli node operations

- Add UI resources and mappings for groups, windows, sessions, storage, performance, extension, and more tab/DOM/page actions.

- Remove the synthetic Gateway Health operation so exposed operations match real browser-cli commands.

- Document the expanded command/policy matrix and cover the new request mappings with tests.

- Cap the node SVG icon at 60x60, bump the n8n package to 0.3.0, and advertise client protocol version 0.16.0.
