Subject: [PATCH] perf: eliminate allocations in casing operations

- Replace `.collect::<Vec<_>>().join("")` with `.collect::<String>()` when generating PascalCase strings to avoid unnecessary Vec allocation.
- Replace `.to_lowercase().collect::<String>()` with `.to_lowercase().to_string()` when lowercasing individual characters.
