Summary
Introduced wildcard support ('wildcard' and 'strict wildcard' operators) to the Ruleset Engine, enabling flexible pattern matching in various Cloudflare products. Developed a custom Rust crate for byte-oriented, UTF-8 compatible wildcard matching with substring capture, supporting up to 8 asterisks and escape sequences. Implemented the `wildcard_replace()` function for dynamic URL redirection in Single Redirects and added a simplified UI for wildcard pattern configuration.
