/**
 * Custom hook for polling git status and commit dates of worktrees with Effect-based execution
 *
 * Fetches git status and last commit date for each worktree at regular intervals
 * using Effect.runPromiseExit and updates worktree state with results.
 * Both are fetched together so they appear at the same time.
 * Handles cancellation via AbortController.
 *
 * Each poll cycle fetches every worktree concurrently and commits the results in
 * a single state update, skipping the update entirely when nothing changed. This
 * keeps a poll cycle to at most one re-render of the consumer (the menu) instead
 * of one per worktree, so background polling does not stutter keyboard navigation.
 *
 * @param worktrees - Array of worktrees to monitor
 * @param defaultBranch - Default branch for comparisons (null disables polling)
 * @param updateInterval - Polling interval in milliseconds (default: 5000)
 * @returns Array of worktrees with updated gitStatus, gitStatusError, and lastCommitDate fields
