* [Feature] Add pass_visualizer: structure-tree pass browser
Add an interactive, pass-by-pass IR structure-tree visualizer under
tilelang/utils/pass_visualizer. It complements the existing text-level
pass_diff tool by rendering the SBlock structure tree and expanding tile
ops by field name, with per-class operator highlighting (tile op / sync /
lowered hardware intrinsic) across the CUDA lowering prologue.
Includes a CLI entry point, an example gemm_relu kernel, a pytest suite,
and a docs section contrasting it with pass_diff.

* Move pass_visualizer to tilelang/tools and fix prologue + review issues
- Move package from tilelang/utils to tilelang/tools per review
- Add missing MaterializeKernelLaunch pass (fixes CUDA CI modulo-by-zero)
- Escape "</" in embedded JSON to prevent <script> injection in HTML report
- Use explicit utf-8 encoding for source/output file I/O
- Guard _fmt_shape against symbolic shapes and validate module spec
