Auto-replies to artifacts can now be delivered through an alternate, forked/subagent path

What

When Claude Code is about to send an automatic reply related to an artifact, it now checks a new condition and, if true, can route that reply through a new delivery path instead of the previous one. This new path can complete the delivery on its own, or hand off to a 'fork' (a separate branched task), in which case the older delivery code is skipped.

This is controlled by a gate called tengu_sorrel_trellis_tenon, which the flag server currently returns as off both for this site's account and for the general anonymous baseline.

Why

This adds an alternate route for delivering auto-replies, potentially through a forked or subagent task, though it is not turned on for this site's account so it has no visible effect yet.

Feature flag
tengu_sorrel_trellis_tenon Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
