fix: stop hijacking user model selection

Remove runtime config override (lines 666-676) that was setting
model.primary to blockrun/auto on every plugin load, even when
user had selected a different model.

The persistent config (injectModelsConfig) already handles defaults
correctly. Runtime override was redundant and broke model selection.

Fixes #14 - users can now select models from other providers without
ClawRouter hijacking their selection.

Tested:
- Fresh install: defaults to blockrun/auto ✓
- User selects anthropic/sonnet: persists correctly ✓
- Gateway restart: preserves user selection ✓
