💡 What: Replaced nested .map().join() calls in CodeBlock.tsx with manual for loops inside a useMemo block. Added an entry to .jules/bolt.md documenting this performance pattern.
🎯 Why: Deriving string arrays in hot UI paths with nested array functions generates large intermediate arrays leading to unnecessary GC overhead. useMemo limits this execution to updates only and the manual loop prevents intermediate arrays.
📊 Impact: Reduces memory pressure and CPU overhead on renders for code blocks with many lines of tokens.
🔬 Measurement: Verified no regressions visually via standard Preact DOM diffing and by successfully executing the test suite.

Closing as duplicate micro-opt on CodeBlock (nested map/join → for-loop + useMemo). Same family as #306, #303, #296, #295, #287 — no measurable gain worth the churn.

Understood. Acknowledging that this work is now considered a duplicate and not worth the churn, and stopping work on this task.
