Adds integration/ (separate module): docker compose stack with real Traefik
v3.5 + localPlugins, mock openai/anthropic/gemini/tool providers, shared
Redis, and a raw-TCP streaming timing probe. 6/7 tests pass; streaming
incrementality fails on a confirmed external yaegi/Traefik bug (see
task-15-report.md), not a plugin defect.
Fixes 4 real Yaegi-interpretation bugs surfaced by running the plugin under
real Traefik for the first time (none caught by go test or yaegi-check,
which never exercises chat/embeddings/streaming/Redis):
- .traefik.yml: add basePkg (Traefik derives the yaegi binding identifier
from the module path, not the package's own declared name; without this
override the plugin never loads at all).
- registry.go: resolveAgainst's multi-value return panicked yaegi on an
inline string concatenation; assign to a local first.
- routes_unified.go: errors.As panicked yaegi on interpreted pointer error
types; use plain type assertions (both types are always returned bare,
never wrapped).
- sse.go: readSSE's dispatch closure hit the same multi-value-assignment
panic as registry.go; split into separate statements.
- resp.go: respErr as a defined string type was indistinguishable from a
plain string in a yaegi type assertion, misreading every successful
Redis SELECT reply as failed and silently disabling rate limiting;
changed to a struct.
