Preconnect skip rules replaced with a provider check

The startup warm-up request now skips based on your resolved provider rather than a list of variables.

What

The warm-up request to /api/hello no longer checks a list of provider environment variables such as Bedrock, Vertex, Foundry and Mantle. It now skips when the resolved provider is not first-party, when the login method is a gateway, and on one further condition whose meaning is not settled in this build. Proxy, unix socket and client certificate skips are unchanged.

Evidence

/api/hello

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
