What changed in this PR
Refactors SQL compilation around a dedicated visitor-based CompileContext, leaving SqlResult as the final execution result.
Changes:
- Replaces string-returning compiler methods with visitor methods.
- Migrates dialect-specific pagination and condition compilation.
- Updates limit tests and adds binding-order coverage.

Old
SqlResultwas playing multiple roles, as a compilation context, and as a execution result.create a new compilation context
CompileContextthat act as the context when compiling the query, and keepSqlResultfor the final result only.Refactor the compiler to use a light weight Visitor pattern instead of the old string concatenation, leading to faster and cleaner compilation.
