fix: resolve PR check failures

Browse Source 
- SSRF: Add IPv6 private range checks (loopback, ULA, link-local,
  IPv4-mapped) after DNS resolution, closing the IPv6 bypass
- Deduplication: Add Set-based dedup in CustomProvidersSection
  handleDetectModels to prevent duplicate model accumulation
- Bump type: change changeset from patch to minor for new feature
- Reasoning: Narrow Anthropic sonnet reasoning detection to only
  flag models containing both 'sonnet' and 'think'
- Docs: Add JSDoc to all undocumented functions in route file,
  raising docstring coverage above the 80% threshold
- Test: Update sonnet reasoning expectation (standard sonnet is not
  a thinking model)
