⚡ Bolt: Optimize status bar drawing allocation

[google-labs-jules]

Optimization:

• Replaced malloc in drawstatusbar with a stack buffer of 1024 bytes.
• Removed free call.
• Added explicit size check to prevent buffer overflow.

Why:

• drawstatusbar is called frequently (on every status update or redraw).
• The status text stext is globally defined as 1024 bytes.
• Heap allocation for such small, bounded buffers is unnecessary overhead.

Verification:

• make clean && make passes.
• Code logic verified to handle string copying safely.
