Buffered Copy Handler is an independent Linux file copy and move manager with tunable I/O buffers, byte-offset pause/resume checkpoints, and wildcard or attribute filtering, inspired by classic Copy Handler workflows.

Key Features:

• Tunable I/O Buffer Engine: choose chunk sizes of 64 KB, 256 KB, 1 MB, 4 MB, or 16 MB with real-time throughput telemetry (MB/s), chunk progress, and sparkline visualization.
• Checkpointed Pause and Resume: pause active transfers cleanly at exact byte offsets and persist resumable JSON checkpoints so interrupted multi-megabyte or gigabyte file transfers continue from the saved byte offset across pauses or restarts.
• Filter Engine and Safe Verification: filter queues with include/exclude wildcard masks, minimum/maximum file size, and modified date cutoffs; preserve file timestamps/permissions and verify post-copy SHA-256 digests before removing sources in Move mode.
• Task Inspector and Profiles: inspect per-file statuses, speeds, and ETA; save and load JSON buffer/filter profiles and export completed task histories to CSV.
• Bilingual English and Vietnamese interface with instant runtime switching.
