Updates Bug Fixes, Security Fixes, and New Features across a mixed release.

Full changelog

File-path destination for single-file copies — When copying a single file, the destination can now be a file path (e.g. fast_copy host:file.tar.gz /local/renamed.tar.gz). Works across all modes: L2L, R2L, L2R, R2R. A trailing / or \ forces directory interpretation

Windows verify crash on device paths — Fixed ValueError: path is on mount '\\.\nul' crash during post-copy verification when os.walk encountered Windows device paths. Cross-mount paths are now skipped with a warning
Remote single-file copy failed with "Not a directory" — Copying a single file from a remote source (e.g. host:/path/to/file.tar.gz) failed because the tar command tried to cd into the file path instead of its parent directory

File-destination heuristic hardened — Uses splitext() instead of checking for any dot in the basename, preventing false positives on hidden directories (.outputs, .config)
R2R rename error checking — Remote-to-remote post-copy rename now checks the exit code and warns on failure instead of silently continuing

Hardened file‑destination heuristic using splitext() to prevent false positives on hidden directories like .outputs and .config
Remote‑to‑remote rename now checks exit code and warns on failure
