feat: publish v1.0.0-rc.36-custom.2

Fixed-group tokens with a backup group now take precedence over the session affinity skip-retry-on-failure rule, so retryable upstream errors (503) fall through to the backup group instead of stopping on the primary channel. Non-retryable errors, explicit channel pins, and auto groups are unchanged.

Adds controller regression tests for the affinity override and a build-time Go test gate.
