Subject: [PATCH] perf: Optimize statusbar text allocation

Replaced heap allocation (malloc/free) with stack buffer in `drawstatusbar`.
This removes allocator overhead from a frequent drawing path.
Buffer size is aligned with `stext` global definition (1024 bytes).

+## 2026-01-12 - Missing Xinerama Dependency
+**Learning:** The environment lacks `Xinerama` headers, preventing the default build configuration from compiling. This is common in minimal environments.
+**Action:** When working with X11 window managers, always check for Xinerama support or flags in `config.mk` and be prepared to disable it if headers are missing, or better, ensure dependencies are installed if possible. In this restricted environment, I might need to disable Xinerama in `config.mk` to proceed with verification.
