refactor: replace sync requests with async httpx in Jina AI client (#1603)
* refactor: replace sync requests with async httpx in Jina AI client

Replace synchronous `requests.post()` with `httpx.AsyncClient` in
JinaClient.crawl() and make web_fetch_tool async. This is part of the
planned async concurrency optimization for the agent hot path
(see docs/TODO.md).

* fix: address Copilot review feedback on async Jina client

- Short-circuit error strings in web_fetch_tool before passing to
  ReadabilityExtractor, preventing misleading extraction results
- Log missing JINA_API_KEY warning only once per process to reduce
  noise under concurrent async fetching
- Use logger.exception instead of logger.error in crawl exception
  handler to preserve stack traces for debugging
- Add async web_fetch_tool tests and warn-once coverage

* fix: mock get_app_config in web_fetch_tool tests for CI

The web_fetch_tool tests failed in CI because get_app_config requires
a config.yaml file that isn't present in the test environment. Mock
the config loader to remove the filesystem dependency.
