The changes include updates to dependencies in `Cargo.lock` and `Cargo.toml`, along with enhancements to the markdown rendering script:
1. Added new dependencies: `reqwest` for HTTP requests and `rust_util` for utility functions.
2. Modified `main.rs` to support reading from both local files and URLs, improving flexibility.
3. Updated metadata files (`script-meta-v2.json` and `script-meta.json`) to reflect changes in script size and hash.
These updates expand the script's capabilities while ensuring compatibility with existing features.
