ethernet 7d2b3b767d merge: integrate upstream/main into ethie/pm-clean 
Merge upstream b1f003e186 while preserving PM runtime ownership and
Python 3.14 worker startup, Windows signing, and macOS wait recovery.

Keep retired runtime modules deleted. Port upstream updater preflight
checks into the checkout strategy and preserve live build logging.
Carry checkpoint filename handling and process recovery into the current
module layout. Regenerate locks and adapt incoming platform test markers.

Focused Python and JavaScript tests, desktop and root-test typechecks,
conflict-path lint checks, lock validation, and retired-import checks pass.
The full test suite and packaged release builds were not run.

"""Tests for the A2A (Agent-to-Agent) platform plugin — protocol v1.0.
Covers security primitives (peer-token identity, injection filtering,
redaction), v1.0 protocol shapes (Agent Card, Task, Part, roles, error codes),
the client tools (with HTTP mocked), adapter RPC handlers driven directly
(no HTTP), and real end-to-end inbound round-trips against a live http.server
with a mocked agent handler.
