What problem is this solving?

Eliminates duplicate lint configuration files across 5 locations, reducing maintenance burden and configuration drift.

Short description of changes

• Remove 3 identical biome.jsonc files (cli, demo, scripts) with duplicate rule overrides
• Simplify tests/integration/biome.jsonc by removing 2 redundant rule configs
• Simplify tests/performance/biome.jsonc by removing 1 redundant rule config, keep noUnusedVariables override with clarifying comment

Testing

• Verified existing lint rules still apply correctly by running lint commands
• Confirmed biome config extends mechanism handles the removed configs
