Resilient File Copier

A fault-tolerant, resumable chunked batch file and folder recovery copier for scratched optical media, aging USB flash drives, degraded SD cards, and unstable network mounts on Linux.
A lightweight Linux alternative to Roadkil's Unstoppable Copier for salvaging undamaged bytes from partially readable files and resuming interrupted transfers.

Key features:
- Configurable block-stream copier (4 KiB to 4 MiB) with an adjustable retry slider from instant fast salvage to aggressive multi-retry 512-byte sub-sector drilldown.
- Automatic OSError / EIO bad-block bypass with optional zero-fill sector padding so readable portions of damaged files are recovered intact instead of aborting the batch.
- Smart resume for partially copied destination files plus skip-existing size/mtime checks and Pause / Continue / Cancel controls.
- Streaming SHA-256 source-vs-destination integrity verification, visual per-file health & throughput chart, and exportable CSV / TXT recovery audit logs.
