Ghost FTP 0.95.26 — FTP command-path control validation (development preview)

Published predecessor: v0.95.25. Do not rewrite or retarget the published release.

Changes

For Windows/Linux FTP and explicit FTPS, reject empty paths and ASCII control characters before FTP LIST, existence checks, rename, delete, create-directory, SITE CHMOD, SIZE, RETR, STOR and APPE commands, including resumable transfer paths.
Preserve support for Unicode and ordinary spaces in remote filenames.
Add Rust regressions in the remote filesystem and central FTP stream layers covering CR, LF, NUL, TAB, DEL, blank targets and safe Unicode paths.
Synchronize version metadata for Rust, Tauri, npm, Go and Android build identifiers. Android and macOS behavior is not otherwise changed.

Latest-head Rust formatting, Clippy and workspace tests.
Real FTP/FTPS/SFTP protocol E2E and desktop Windows/Linux build acceptance.
macOS, Android and product tooling workflows.
Wider third-party daemon interoperability and native device/screen acceptance.
Native macOS FTPS/SFTP, signing/notarization and full FileZilla parity remain separate work (P0 issue #157).

This is unreleased Preview source documentation, not a stable or production-readiness certification.
