Add upstream.ignorePaths config to prevent model swaps for static-asset
requests made through the /upstream/<model>/<path> passthrough endpoint.
- add UpstreamConfig with compiled *regexp.Regexp slice; invalid regex
returns an error at load time
- apply a default pattern matching common static-asset suffixes
(.js/.json/.css/.png/.gif/.jpg/.jpeg/.ico/.txt) when unset
- in handleUpstream, return 409 Conflict when a path matches and the
local model is not already loaded; peer and already-loaded models fall
through to normal dispatch
- update config-schema.json and config.example.yaml
