fix(a2a): handle push-mode queue envelope in response parser

Browse Source 
When a push-mode workspace (one with a public URL) is at capacity, the
platform queues the delegation request and returns:

    {"queued": true, "message": "...", "queue_depth": N, "queue_id": "..."}

The existing SSOT parser (a2a_response.py) only handled the poll-mode
envelope (status=queued + delivery_mode=poll). Push-mode queue
responses fell through to Malformed, causing send_a2a_message to log a
warning and return an error — even though delivery was actually queued
successfully.

Fix: add handling for data.get("queued") is True as a Queued variant
with delivery_mode="push". Checked before the poll-mode envelope so the
two cases are mutually exclusive.

Fixes observed 2026-05-10: platform returning push-mode queue
envelopes to Integration Tester when Release Manager workspace was at
capacity.
