  • What: Optimized string concatenation in xdk-lib/src/casing.rs for Casing::Pascal by using .collect::<String>() directly.
  • Why: The previous code .collect::<Vec<_>>().join("") created an unnecessary intermediate vector allocation, which is slightly slower and uses more memory than building the string directly.
  • Impact: Eliminates O(N) array allocation overhead every time a PascalCase string is generated.
  • Measurement: Passes all existing test cases (make check, cargo test) with identical generated outputs.

- What: Changed `.collect::<Vec<_>>().join("")` to `.collect::<String>()` in `Casing::Pascal`.
- Why: Using `.collect::<Vec<_>>().join("")` unnecessarily creates an intermediate `Vec` allocation before building the final `String`. Using `.collect::<String>()` directly builds the `String` from the iterator, which is much faster and reduces memory pressure.
- Impact: Eliminates an intermediate array allocation for every PascalCase string generation, which is a frequent operation during SDK generation.
- Measurement: Verifiable by checking that `Casing::Pascal` generation is slightly faster or allocates less memory over large schemas, as well as maintaining correctness through standard test suite passing.
