fix: preserve mixed asset query semantics

[ScriptedAlchemy]

Summary

• tighten the generic non-CSS ?url asset rule so it does not steal mixed ?url&raw or ?url&inline requests
• preserve CSS ?url handling outside the generic asset rule
• add coverage for query ordering and mixed-query exclusions

Validation

• pnpm test:core
• pnpm build
• git diff --check
