make_client used a bare reqwest builder, which honours whatever proxy the
environment advertises. That made it the only HTTP client in Coyote to do so:
utils::set_proxy discards ambient settings and applies only Coyote's configured
proxy, and every other client goes through it.
The symptom is that a perfectly healthy Qdrant is unreachable and the error
belongs to the interposing proxy, not the store, so it reads as a Coyote or
Qdrant fault. Locally an installed Socket Firewall answered `.rag attach`
against 127.0.0.1:6333 with an HTML 'Connection Required' page and HTTP 405.
Both #[ignore]d live tests now pass against a real Qdrant; they failed with that
same 405 before this change, which is the first time either has run green.
A remote store that genuinely needs Coyote's configured proxy is a follow-up:
that means threading the proxy config into the provider.
