Shared node_modules Across Worktrees

Status: Delivered
CAS: CAS-3611
Delivered: 2026-05-18

What changed

Introduced shared node_modules handling across worktrees to reduce duplicate disk use and repeated install time during parallel agent execution.

Why it matters

• Reduces local disk tax from multiple active worktrees.
• Speeds dependency reuse for frequent branch/context switches.
• Keeps local dev loops stable while CI remains manual-only.

Technical anchors

• scripts/ tooling for shared dependency wiring
• Worktree policy in AGENTS.md
