Function writeGenerationMetadata

writeGenerationMetadata(
    stats: GenerationStats,
    results: GenerationResult[],
    usedMCP: boolean,
    metadataDir: string,
    dryRun: boolean,
): void
Persist a generation metadata JSON file to the metadata directory. If a metadata file already exists for today, merges the current run's stats and results with the existing ones so multiple workflow runs on the same day do not overwrite each other's data. Skips writing when dryRun is true.
Parameters
- stats: GenerationStats
  Final generation statistics
- results: GenerationResult[]
  Per-article-type generation results
- usedMCP: boolean
  Whether the MCP client was connected during this run
- metadataDir: string
  Absolute path to the metadata output directory
- dryRun: boolean
  When true the file is not written
Returns void
