Claude bd0a0f0c26 Add comprehensive fuzzing infrastructure for URL parser

This commit adds AFL++ (American Fuzzy Lop) fuzzing support to help find bugs,
crashes, and security vulnerabilities in the URL parser.

Changes:
- Add fuzz_afl.c: AFL++ fuzz target that tests all parser functions
  - url_parse() with different flag combinations
  - url_parse_ipv4() and url_parse_ipv6()
  - url_serialize(), url_percent_decode(), url_remove_white_space()

- Add build_afl.sh: Build script with AFL++ compiler detection
- Add run_afl.sh: Automated fuzzing script with result reporting
- Add url.dict: Dictionary file to guide AFL++ mutations

- Add corpus/: Seed inputs covering various URL patterns
  - Basic URLs, IPv4/IPv6, percent-encoding, relative paths
  - Edge cases and special schemes (file://, mailto:, etc.)

- Add FUZZING.md: Comprehensive documentation
  - Installation instructions
  - Quick start guide
  - Advanced usage (parallel fuzzing, sanitizers)
  - Troubleshooting tips

- Add fuzz.c: Standalone mutation-based fuzzer (no AFL++ required)
  - Useful for quick testing without installing AFL++
  - Implements various mutation strategies
