🎯 What: Added missing unit test coverage for the is_safe_ip function in stdlib/src/web.rs, which is used to prevent SSRF vulnerabilities. Addressed a bug found during testing where ::1 (IPv6 loopback) was incorrectly evaluated.
📊 Coverage: The tests now comprehensively cover:

  • Safe IPv4/IPv6 addresses
  • Unsafe IPv4 (private, loopback, link-local, broadcast, documentation, unspecified)
  • Unsafe IPv6 (loopback, unspecified, ULA, link-local)
  • IPv4-mapped IPv6 addresses (both safe and unsafe mappings)
    Result: Enhanced the reliability and security of network request filtering by guaranteeing proper evaluation of IP addresses.

PR created automatically by Jules for task 15780653356790105678 started by @Tcode-Motion

- Added a `mod tests` block in `stdlib/src/web.rs` for `is_safe_ip`.
- Covered test cases for safe/unsafe IPv4 and IPv6 addresses.
- Fixed a bug in `is_safe_ip` where `ipv6.to_ipv4()` would incorrectly process the IPv6 loopback (`::1`) as a compatible IPv4 address (`0.0.0.1`), bypassing the security check. Switched to `ipv6.to_ipv4_mapped()` as intended.
