feat(tools): resilient web search and fetch across all providers (#836)

Browse Source 
- Add exponential backoff retry to DuckDuckGo adapter (3 attempts with
  jitter) to handle transient rate-limiting and connection errors.
- Add native fetch() fallback in WebFetch when axios hangs with custom
  DNS lookup in bundled contexts.
- Prevent broken native-path fallback for web search on OpenAI shim
  providers (minimax, moonshot, nvidia-nim, etc.) that do not support
  Anthropic's web_search_20250305 tool.
- Cherry-pick existing fixes:
  - a48bd56: cover codex/minimax/nvidia-nim in getSmallFastModel()
  - 31f0b68: 45s budget + raw-markdown fallback for secondary model
  - 446c1e8: sparse Codex /responses payload parsing
  - ae3f0b2: echo reasoning_content on assistant tool-call messages
- Fix domainCheck.test.ts mock modules to include isFirstPartyAnthropicBaseUrl
  and isGithubNativeAnthropicMode exports.
