🎨 style(syntax): normalize naming conventions

Align all TSL syntax documentation examples with docs/tsl/naming.md:

- Classes/types: PascalCase, drop Hungarian prefix (THuman→Human)
- Parameters/locals: snake_case with meaningful names (isLeft→is_left, maxb→max_b)
- Private members: snake_case_ with trailing underscore (real_part_, imaginary_part_)
- Public members: PascalCase (value→Value)
- Top-level functions: PascalCase (test→Test)
- Module constants: kPascalCase (kernel_dll→kKernelDll)

Affected: 01-24 syntax docs (23 files)
Verified: 150+ code blocks locally tested, output unchanged
