* fix(a2a-queue): nil-safe error extraction in DrainQueueForWorkspace + handle 202-requeue
The drain path called proxyErr.Response["error"].(string) without a comma-
ok assertion. When proxyErr.Response had no "error" key (which happens in
the 202-Accepted-queued branch I added in the same PR — that response is
{"queued": true, "queue_id": ..., "queue_depth": ...}), the type assertion
panicked and killed the platform process.
The platform was down 25 minutes today before this was diagnosed. Fleet
went from 30 real outputs/15min → 0 events.
Two fixes here:
1. Treat 202 Accepted from the inner proxyA2ARequest as "re-queued"
(target was busy AGAIN). Mark THIS attempt completed; the new queue
row will be drained on the next heartbeat tick. Don't propagate as
failure.
2. Defensive type-assertion when reading the error string. Falls back to
http.StatusText, then a generic "unknown drain dispatch error" so the
queue still gets a non-empty error_detail for ops debugging.
Now the drain path can never panic on a malformed proxy response.

* fix(a2a-queue): return (202, body, nil) so callers see queued-as-success
Cycle 53 found callers logging 45× 'delegation failed: proxy a2a error'
even though the queue's drain stats showed 48 completions in the same
window. Investigation: my busy-error path returned
return http.StatusAccepted, nil, &proxyA2AError{Status: 202, Response: ...}
The non-nil proxyA2AError is the failure signal. Even with status=202,
callers' `if proxyErr != nil` branch fires and logs the request as
failed. The 202 status was meaningless — the response body was nil too,
so the caller never even saw the queue_id/depth metadata.
Fix: return success-shape so callers do NOT enter the error branch:
respBody, _ := json.Marshal(gin.H{"queued": true, "queue_id": qid, ...})
return http.StatusAccepted, respBody, nil
Net effect: queue continues to absorb busy-errors (working since #1893),
AND callers correctly record the dispatch as queued-success rather than
failed. Closes the cycle 53 misclassification that was making the queue
look ineffective on activity_logs counts.
