Dudu-0223 0930e483ec fix: address codex review round 2
- Preserve abort errors while parsing search responses: when the caller's
  AbortSignal fires after headers but during response.json() (both the success
  and HTTP-error body parses), surface WEB_ABORTED instead of wrapping it as
  WEB_PROVIDER_ERROR, so agent cancel/dispose is not misreported as a provider
  failure. Applied to both the Exa and Perplexity providers.
- Report a malformed baseURL as misconfigured in status() (URL.canParse), so
  selection diagnostics and execution agree (configured-unavailable up front
  rather than a late WEB_PROVIDER_ERROR). WebProviderStatus already had the
  reason.

# @deepseek-ai/dsh-web-search-exa
An [Exa](https://exa.ai)-backed `WebSearchProvider` for the harness [web capability seam](../web/README.md) (`ctx.web`). It calls Exa's `POST /search` endpoint with highlight contents and maps the flat `results[]` into the seam's normalized `WebSearchResult`.
This is an **implementation** package: it registers a provider into `ctx.web`, it does not own the `ctx.web` key and it does not register a model-facing tool (that is `@deepseek-ai/dsh-tool-web`). Like `@deepseek-ai/dsh-llm-deepseek`, it is a function/namespace plugin (`inject: ['web']`) that registers its backend, not a default-export service.
## Config
| Key | Default | Meaning |
|---|---|---|
| `apiKey` | `$EXA_API_KEY` | Exa API key. Empty/absent → provider `status()` reports `missing-credential` (the seam reports `configured-unavailable`/`none`). |
| `baseURL` | `https://api.exa.ai` | Endpoint base; `/search` is appended. An unparseable value makes `status()` report `misconfigured`. |
```yaml
- id: web-search-exa
name: '@deepseek-ai/dsh-web-search-exa'
config:
apiKey: !!js process.env.EXA_API_KEY
```
## Mapping
Exa returns a flat `results[]` and no generated answer, so `content` is omitted. Each result maps to a `WebSearchSource`: `url``url`, `title``title`, `snippet` ← the first non-empty `highlights[]` entry (a result with no highlight has no portable snippet and is dropped), `publishedAt``publishedDate`. The provider passes `maxResults` through as Exa's `numResults` for a cost/latency optimization; the final bound is enforced by the seam. Provider failures (HTTP errors, network failure, unparseable bodies) surface as `WebError` `WEB_PROVIDER_ERROR`; an aborted request surfaces as `WEB_ABORTED`.
