/**
 * Browser tool E2E spec — coverage matrix rows 7.1.1 (open URL) and
 * 7.1.2 (browser automation). Tracked by issue #967.
 *
 * The `browser_open` and `browser` (automation) tools live in
 * `src/openhuman/tools/impl/browser/` and are agent-internal: they are not
 * exposed as JSON-RPC controllers, and the open path shells out to Brave on
 * the user's machine — explicitly out of bounds under the issue's "no real
 * network or shell side-effects" constraint. This spec mirrors the
 * `tool-shell-git-flow.spec.ts` envelope: assert the deterministic RPC and
 * registry contract end-to-end, plus prove the mock-backend transport
 * captures the request shape that browser-automation flows would emit when a
 * real LLM eventually drives them. The tool's own validation logic is
 * covered exhaustively by Rust unit tests in
 * `src/openhuman/tools/impl/browser/browser_open_tests.rs` and
 * `browser_tests.rs`.
 *
 * What this spec proves end-to-end:
 *  - 7.1.1 — the agent runtime is up and the `tools_agent` definition that
 *    inherits the `browser_open` tool is wired into the live registry served
 *    over JSON-RPC. Plus: the mock backend correctly records arbitrary HTTP
 *    requests (proving the side-channel browser-automation flows would emit
 *    against the mocked services is intact).
 *  - 7.1.2 — `BrowserTool::parameters_schema` enumerates the automation
 *    surface (open / snapshot / click / fill / type / get_text / etc.).
 *    Asserting that `tools_agent`'s tool scope is wildcard (which would
 *    surface `browser` to the LLM) ensures the schema-driven tool surface is
 *    intact for the agent path.
 *
 * Future: when the harness gains a deterministic mock-LLM that emits
 * structured `tool_calls`, the `it.skip` block below can flip into a real
 * end-to-end browser-open assertion (with the open path stubbed via a
 * runtime adapter) without touching the rest of this file.
