Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20[performance=20improvement]?=

Replaced string-based splits with char-based splits and removed intermediate Vec allocations in `xdk-build/src/python.rs`. Replaced intermediate Vec allocation and `.join("")` with direct `.collect::<String>()` in `xdk-lib/src/casing.rs`. Added inline comments explaining the optimizations.
