Type Alias BidiCache 

pub type BidiCache = Arc<Mutex<Option<Arc<BidiClient>>>>;

Persistent BiDi client, opened lazily on first use. Reused across all tool calls because Firefox limits concurrent BiDi sessions per browser to one. The browsing-context id is resolved per call so multiple tabs can be addressed once URL-regex selection is added.
