chore: clear existing lint warnings

[9aoy]

Summary

Background

Biome reported existing warnings in the core mock runtime, a watch e2e fixture string, and the Svelte example component, which kept the repository from a clean lint run.

Implementation

• Removed the unused isEsModule variable from the core mock runtime.
• Added targeted Biome suppressions for the watch fixture source string and the Svelte template-backed script variables.

User Impact

pnpm lint now completes without warning noise from these known cases.

Checklist

• Tests updated (or not required).
• Documentation updated (or not required).
