_build_slash_event and _dispatch_thread_session built their SessionSource
without guild_id/parent_chat_id, while on_message passes both. Route
matching in build_source keys off exactly those fields, so under
gateway.multiplex_profiles a guild- or channel-routed profile never matched
a native slash command: /new, /reset, /model, /profile, /status ... all ran
against the default profile and reset the wrong session (#69178, #91633).
Pass guild_id (interaction.guild_id, falling back to channel.guild like the
message path) and the thread's parent channel id into build_source at both
sites. One test pins channel + thread routing parity with messages.
