chore: full Biome lint cleanup — zero errors, zero warnings

- Remove 203 unused biome-ignore suppression comments (noConsole rule is off)
- Apply all FIXABLE transforms: Math.pow->**, parseInt radix,
  noUselessContinue, noUselessUndefinedInitialization, useIndexOf,
  useRegexLiterals, useShorthandFunctionType, noPrototypeBuiltins
- Add targeted suppressions for 31 intentional patterns
- Format all src/ files via Biome (quote style, import line width)
- Result: 0 errors, 0 warnings across 2649 files
