"""#64674 — multiplex primary gateway must not fail forever without bot tokens.

When gateway.multiplex_profiles is on and TELEGRAM_BOT_TOKEN lives only in a
secondary profile's .env, the default-profile primary adapter used to start
with an empty token, log "No bot token configured", and queue an infinite
reconnect loop. Secondary profiles already load under _profile_runtime_scope;
this suite locks the complementary primary-path fixes:

1. load_gateway_config_for_runner reloads under the default profile secret scope
   when multiplex is on (so default .env tokens resolve like secondary loads).
2. Primary startup skips token platforms that still have no credential under
   multiplex instead of connecting-and-failing forever.
3. The reconnect watcher drops empty-token queued configs.
