feat(build-tools): Add Biome 2.x config reader with version auto-detection (#25969)

Adds Biome 2.x configuration reader for fluid-build with automatic
version detection. Biome 2.x changed from separate `include`/`ignore`
fields to a unified `includes` field with negation patterns.

## Key Changes

**New modules:**
- `biome2Config.ts` - Biome 2.x config reader with unified `includes`
field and re-inclusion pattern support
- `biome2ConfigTypes.d.ts` - Auto-generated types from Biome 2.x JSON
schema
- `biomeVersion.ts` - Version detection from package.json or CLI
- `biomeConfigUtils.ts` - Shared utilities (config loading, extends
resolution, factory, interface)

**Refactored:**
- `biomeConfig.ts` - Renamed to `BiomeConfigReaderV1` for v1-specific
implementation
- `biomeTasks.ts` - Uses `createBiomeConfigReader()` factory for
auto-detection

## Features

- Auto-detects Biome version and returns appropriate reader (v1 or v2)
- Supports `root` field for automatic parent config discovery
- Handles both explicit `extends` and implicit parent config merging
- Supports `//` microsyntax for extending root config
- Comprehensive test coverage for v2 config scenarios
