/**
 * Update command - incrementally updates documentation based on git changes.
 *
 * This command:
 * 1. Checks git repository status
 * 2. Detects files changed since last run (via content-hash comparison)
 * 3. Cleans up orphaned .sum files
 * 4. Resolves an AI CLI backend and creates the AI service
 * 5. Analyzes changed files concurrently via CommandRunner
 * 6. Regenerates AGENTS.md for affected directories
 * 7. Writes telemetry run log and prints run summary
 *
 * Exit codes: 0 = all success, 1 = partial failure, 2 = total failure / no CLI
