Subject: [PATCH 1/5] fix(cli): improve LaTeX and JS-heavy site parsing in
 direct_fetch

Updated strip_html in direct_fetch.rs to:
- Skip content in <math>, <svg>, and <noscript> tags to reduce noise.
- Wrap LaTeX in <img> alt attributes (starting with {\displaystyle) in $ delimiters.
- Added unit tests to verify these improvements.
- Fixed a bug in integration tests where assertions were incorrectly wrapped in tuples.
- Formatted code with cargo fmt and ruff.

Subject: [PATCH 2/5] fix(cli): improve LaTeX parsing and fix integration test
 assertions

This commit improves the HTML-to-Markdown conversion in the Rust CLI and
fixes a critical bug in the integration test suite.

Changes:
- Updated `strip_html` in `direct_fetch.rs` to skip noise from `<math>`,
  `<svg>`, and `<noscript>` tags.
- Improved LaTeX detection in `img` alt attributes, wrapping detected
  TeX in `$` delimiters for LLM-readability.
- Added unit tests in Rust for the new parsing logic.
- Fixed `test_cli_markdown.py` where assertions were incorrectly using
  tuples (e.g., `assert (cond), "msg"`), which were always evaluated
  as True.
- Applied `black` formatting to satisfy CI linting requirements.

Verified with `cargo test` and `pytest -m integration`.

Subject: [PATCH 3/5] fix(cli): refactor strip_html to reduce complexity and
 improve parsing

- Refactored `strip_html` in `direct_fetch.rs` by extracting logic into
  `StripperState` and helper methods, reducing cyclomatic complexity
  (addressing DeepSource RS-R1000).
- Maintained improved LaTeX parsing and noise reduction (<math>, <svg>,
  <noscript> skipping).
- Verified functionality with existing unit and integration tests.
- This commit updates the existing PR branch.

Subject: [PATCH 4/5] fix(cli): elide needless lifetimes in StripperState impl

- Addresses Clippy error `clippy::needless_lifetimes` by eliding the
  explicit `'a` lifetime in the `impl` block for `StripperState`.
- This ensures CI checks pass for the Rust CLI.
- Mainloop and parsing logic remain unchanged and verified by tests.
