"""Regression test for #90835 (logging-illusion half).

The Telegram adapter's "Connecting to Telegram (attempt N/8)…" line is
emitted at WARNING and therefore reaches the gateway's default stderr
handler (WARNING-only at default verbosity). The matching
"Connected to Telegram (… mode)" success line was INFO and went to the log
file only, so a healthy startup looked permanently stalled at "attempt 1/8"
on the terminal.

This test pins the invariant that both sides of the connect transition are
emitted at the same terminal-visible level, by inspecting the log calls in
the adapter source (the connect path needs a live bot token to execute, so
the levels are asserted at the AST level rather than by running it).
