Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 2.37 s -> 1.95 s (-423.5 ms) vs ben/hitl-v2-design (7a2ea27).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.
