Patrick Buckley 7fbcb70ec1 Add call_id routing for streaming tool output during parallel execution (#6)
* Add call_id routing for streaming tool output during parallel execution

Thread call_id through tool_info, approve_request, and tool_result SSE
events so the browser can route streaming output chunks and final results
to the correct tool div when multiple bash tools run in parallel.

Server: include call_id in serialized approval items and tool_result events.
Protocol: add call_id to on_tool_result signature (session, cli, eval, server)
         and ToolResultEvent dataclass; pass through MQ bridge.
Client: set data-call-id on tool divs, match by call_id in appendToolOutputChunk
        and appendToolOutput with func_name fallback; extract makeCollapsible
        helper; use CSS.escape for querySelector safety; fix replayHistory
        \\n typo and missing keyboard accessibility on collapsed output.
Bridge: fix pre-existing bug using "name" instead of "func_name" for
        auto-approval matching; include call_id in _build_history for replay.
Also adds on_tool_result calls to write_file and edit_file exec methods.

* Update docs/tools.md
