v3.1.0

Changed

• Delegation skill removed — files/skills/delegation/SKILL.md deleted; all routing rules and step budgets consolidated directly into headwrench.md's agent roster table. The skill was de facto unused — no planning DAG node ever invoked it, and its content was already duplicated in the HW prompt.

Fixed

• .opencode/ session directory exclusion — ContextScout and ContextInsurgent delegation instructions now consistently exclude .opencode/ session content from codebase reads. Stale completed sessions can contain conflicting info that poisons analysis; planning infra files (node-library, etc.) remain accessible when explicitly tasked.
• research-gate unconditional question tool — removed self-assessment framing that allowed the planning agent to skip the question tool call with a plain-text conclusion; the gate now always requires the question tool. research-brief updated to establish Context7 as the primary lookup tool (Exa secondary) and explicitly defer deep research to generated project DAG nodes.
