feat(auq-format): proactive SESSION_KIND=spawned rule ordered above the Conductor rule (#2733)

The spawned classification previously existed only in the failure-fallback
branch — a spawned session was invited to call AskUserQuestion and reach
auto-choose via the deny/error detour, and a spawned session inside a
Conductor workspace hit the Conductor prose-STOP rule first. The Tool
resolution list now leads with the spawned rule (auto-choose recommended,
never prose, never BLOCKED, destructive gates resolve conservative), the
self-check carries the never-reach-this-checklist clause, and all tier>=2
SKILL.md renders are regenerated. Context-budget fixture refreshed in the
same commit per the ratchet protocol (the AUQ section is eager in every
tier>=2 skill).
