buildSkillsSection() had an early-return guard on isMinimal that silently
dropped the entire <available_skills> block for any session using
promptMode="minimal" — which includes all isolated cron agentTurn sessions
(isCronSessionKey → promptMode="minimal" in attempt.ts:497-500).
Fix: remove the isMinimal guard from buildSkillsSection so that skills are
emitted whenever a non-empty skillsPrompt is provided, regardless of mode.
Memory, docs, reply-tags, and other verbose sections remain gated on isMinimal.
Tests added:
- "includes skills in minimal prompt mode when skillsPrompt is provided (cron regression)"
- "omits skills in minimal prompt mode when skillsPrompt is absent"
- Updated existing minimal-mode test expectation to match corrected behaviour.
