Phase 3: Compile-aware loader, :compile? flag, compile-and-eval

- loader.janet: load-ns with compile? dispatch, compiled-cache, compiled?, clear-compiled-cache
- compiler.janet: compile-ast (Janet data structures for direct eval), compile-and-eval
- api.janet: compile-string, compile-file, eval-string dispatches to compile-and-eval when :compile? is true
- types.janet: :compile? flag and :compiled-cache table in context env
- Stateful forms (def, defmacro, ns, deftype, defmulti, defmethod) fall back to interpreter
- All 317 tests pass + 16 new Phase 3 tests
