Subject: [PATCH] fix: guard against undefined snapshot.skills in
 applySkillEnvOverridesFromSnapshot

snapshot.skills can be undefined when a session is reset during an API
rate-limit cooldown, causing a TypeError crash that compounds the
original rate-limit issue.

Use nullish coalescing (snapshot.skills ?? []) to safely skip iteration
when skills is not populated.
