🛡️ Deletion Error Visibility: Resolved an issue where I/O errors (e.g. permission denied) during existence checks were masked as successful deletions.

Deduplicator Engine

🧮 Special & Cloud File Deduplication Filtering: Deduplication Phase 1 grouping now strictly ignores dataless/cloud placeholders, Unix special files (FIFOs, sockets, device nodes), and permission-denied files to avoid attempting invalid read operations.
🛡️ Hash Calculation TOCTOU Defense: Verified metadata.is_file() across all range-based and full-hash calculation functions to defend against files changing type post-scan.

Licensing & Verification

📋 Deterministic License Generation: Fixed non-deterministic cargo-about license output between local filesystems and Docker CI runners by configuring max-depth = 1 in about.toml.
