docs(remote-mcp): restamp the commit the #956 anchors resolve at

The execution-authorization gate shifted two cited lines in
mcp_daemon_guard.py, so the fixture and the document must name the commit
where the re-anchored citations actually resolve. Both still named
c1626081, where the two moved anchors no longer point at the claimed code.

Point both at a143cd06. This commit changes no .py file, so every anchor
that resolves at a143cd06 resolves here too. The historical note about
#930's drift between 7bf4f125 and aad5c8b4 stays as written.

Refs #931, #956. Addresses review 635.
