Make research evaluation deterministic with recorded fixtures

The evaluation scripts spawned the MCP as a subprocess and made live
Brave, Algolia, and page requests, so they could not run in CI and had
drifted: one fixture query no longer passes the current sanitizer, and
both scripts exceed the per-server call budget added in v0.12.2.

Run the documentation server in-process over an InMemoryTransport, one
server per case, and replay recorded fixtures through the existing
fetchImplementation seam. Each case carries its own fixture; the replay
synthesizes the exact wire formats (Brave hits, Algolia hits, the OkHttp
static index, DocC JSON, HTML, Markdown, YouTrack JSON) keyed by the
request URLs the production provider logic computes, so the sanitizer,
routing, allowlists, redirect and content-type checks, extraction, and
ranking all run unmodified. RESEARCH_EVAL_LIVE=1 keeps a live mode for
true retrieval-quality runs.

Thread fetchImplementation through the Expo Algolia search so the
recorded mode covers the expo provider, replace the sanitizer-broken
kotlin-coroutines query with a symbol-anchored one, and run both
evaluations in CI.
