More conditions now trigger a session-tag prefetch before spawning a Remote Control bridge worker

What

Before spawning a bridge worker for a Remote Control session, Claude Code decides whether to first fetch the session's tags. This decision now checks a wider set of conditions than before: whether spawning is enabled, whether a positive idle-exit timeout is configured (via tengu_bridge_rc_child_idle_exit_ms, and only when not in single-session spawn mode), whether restart-resume is enabled (via tengu_bridge_rc_child_restart_resume), or whether an auto-mode environment is configured. Previously this used a narrower, inline check.

Why

Broadening the check means the session-tag prefetch happens whenever any of these bridge features that depend on it are active, rather than only in the one case the old inline check covered.
