Replaces always-malloc approach with Small String Optimization (SSO). Uses a 1KB stack buffer for typical status strings to avoid allocator overhead in the hot rendering path, falling back to malloc only for larger strings.

⚡ Bolt: Optimize
drawstatusbarmemory allocation💡 What: Replaced the unconditional
malloc/freeindrawstatusbarwith a stack buffer of 1024 bytes (matchingstextsize). Added a fallback tomallocfor strings larger than 1024 bytes (Small String Optimization pattern).🎯 Why:
drawstatusbaris called frequently during bar updates. Allocating memory on the heap every time is inefficient and adds unnecessary overhead (syscalls, fragmentation). Stack allocation is virtually free.📊 Impact: Reduces allocator churn in the rendering loop. While micro-benchmark numbers are not available for this environment, stack allocation is universally faster than heap allocation for small, frequent, short-lived buffers.
