 * Build enhanced run summary from loop completion state.

 * This function aggregates data from:
 * - Basic loop state (iterations, tasks, tokens, exit code)
 * - Phase timing file (/tmp/ralph-loop-<feature>.phases)
 * - Baseline commit file (/tmp/ralph-loop-<feature>.baseline)
 * - Git diff stats (via git-summary utilities)
 * - PR/issue metadata (via pr-summary utilities)
 *
 * @param basicSummary - The minimal RunSummary constructed by RunScreen
 * @param projectRoot - Root directory of the project
 * @param feature - Feature name
 * @returns Enhanced RunSummary with all available metadata
 *
 * Note: This function performs synchronous I/O and subprocess execution,
 * which blocks the event loop. Callers should wrap in try-catch to handle
 * failures gracefully.
