Details 
The A2A proxy can return three error shapes:
  {"error": "plain string"}
  {"error": {"message": "...", "code": ...}}
  {"error": {"message": {"nested": "object"}}}   ← value at .message is a string

builtin_tools/a2a_tools.py:72 called data["error"].get("message")
without guarding against error being a string, which raised:
  AttributeError: 'str' object has no attribute 'get'

This broke every delegation attempt through the legacy a2a_tools path
(the LangChain-wrapped version used by adapter templates). The
SSOT parser a2a_response.py already handled string errors; the
legacy inline sniffer in a2a_tools.py did not.

Fix: branch on isinstance(err, dict/str/other) before calling .get().

Also update both publish-workflow files to remove the dead
`staging` branch trigger — trunk-based migration (PR #109,
2026-05-08) removed the staging branch.
