1.0.0-beta1

⚠️ This is an unstable, beta, pre-release version meant only for debugging. Do not use it. ⚠️

Changes since alpha4:

• Added exponential backoff (1–10ms) in flush_queue_buffer() to reduce CPU usage
  when queue is full, with reset after successful push.
• Fixed LMDB key size calculation in process_file.c to use byte length (strlen)
  instead of UTF-8 character count.
• Ensured get_max_queue_size() always returns at least 1 to prevent deadlocks
  on very low RAM systems.
• Refactored scan_dir() to simplify skip logic and improve readability.
• Introduce --verbose/-V CLI option to enable detailed logs and live progress updates
• Echo INFO/DEBUG/MESSAGE logs to stdout when verbose is enabled
• Add periodic progress reporter thread
• Show start/end timestamps and duration
• Improve help text formatting
