Neuron Encrypt v2.0: Unlimited File Encryption, Native CLI & Rebuilt GUI

This major release delivers a complete overhaul of the encryption engine, adds a dedicated command-line interface, and modernizes the graphical interface for better performance, reliability, and usability.

🔐 Core Encryption Upgrades

Removes the previous 2GB file size limit, replacing the old single-pass AES-256-GCM with a new VAULTX03 streaming engine using AES-256-GCM-SIV + Argon2id, supporting unlimited file sizes with a constant ~66MB RAM footprint
31-byte headers (down from 52 bytes), 1MB chunk boundaries to prevent truncation attacks
Full backward compatibility with v1.x VAULTX02 encrypted files

🖥️ New CLI Tool (neuron-encrypt-cli)

Encrypt/decrypt subcommands with custom output paths, overwrite protection, and already-encrypted file detection
Script-friendly features: --json output, --quiet mode, --password-file for CI/CD, NEURON_PASSWORD env var support
Stdin/stdout piping, shell completions (bash/zsh/fish/powershell), and structured exit codes (0=success, 3=wrong password)

🎨 GUI Overhaul

Full rewrite using egui/eframe with streamlined state management
Auto-saves decrypted files beside source, context-aware encrypt/decrypt button, SHA-256 integrity reporting, and batch processing support

⚙️ Reliability & Safety

I/O governor: Periodic sync + 5ms thread yield every 100MB to prevent OS freezes on large files
Atomic temp-file writes: No partial files left on disk, automatic cleanup on errors
Strict path safety checks, minimum 8-character passphrase enforcement

🛠️ Developer Improvements

Refactored neuron_encrypt_core library with generic stream functions and shared ProgressReporter trait
Expanded test suite covering round-trips, multi-chunk streaming, backward compatibility, and error cases
CI/CD additions: cargo-deny license/CVE checks, SHA-pinned GitHub actions, embedded git hash in --version output
