Claude-Mem Queue Clearer

Clear messages from the observation queue.

Usage:
  bun scripts/clear-failed-queue.ts [options]

Options:
  --help, -h     Show this help message
  --all          Clear ALL messages (pending, processing, and failed)
  --force        Clear without prompting for confirmation

Examples:
  # Clear failed messages interactively
  bun scripts/clear-failed-queue.ts

  # Clear ALL messages (pending, processing, failed)
  bun scripts/clear-failed-queue.ts --all

  # Clear without confirmation (non-interactive)
  bun scripts/clear-failed-queue.ts --force

  # Clear all messages without confirmation
  bun scripts/clear-failed-queue.ts --all --force

What is this for?
  Failed messages are observations that exceeded the maximum retry count.
  Processing/pending messages may be stuck or unwanted.
  This command removes them to clean up the queue.

  --all is useful for a complete reset when you want to start fresh.
