Development Log: Second Brain Trace Collapsible UI

Purpose

Reduce visual noise from Second Brain Trace details while keeping the evidence available when the user wants to inspect it.

Implementation Summary

• Wrapped Second Brain Trace output in a collapsed HTML <details> block.
• Added a compact summary line showing usage status and note counts.
• Kept detailed referenced notes, unused notes, grounding metrics, and debug JSON inside the expanded section.
• Updated tests to verify the collapsible structure is rendered.

Changed Files

• src/features/secondBrainTrace.ts
• tests/secondBrainTrace.test.ts

Verification

• ./node_modules/.bin/tsc --noEmit
• npm run compile
• ./node_modules/.bin/jest --runInBand

Result

Trace evidence is still available, but it no longer dominates every answer by default.
