✨ What's New & Highlights

🔑 Native SSH Key Pair Generator

• Multi-Algorithm Cryptographic Key Creation:
  • Generate industry-standard Ed25519 (Recommended, 256-bit), RSA (2048 / 3072 / 4096-bit), and ECDSA (P-256 / P-384 / P-521) key pairs directly in Termlet without needing terminal CLI tools like ssh-keygen.
• Passphrase Encryption (AES-256):
  • Encrypt private keys with an optional passphrase using OpenSSH-standard AES-256 ciphering (ssh.MarshalPrivateKeyWithPassphrase).
• OpenSSH "Drunken Bishop" Randomart Visualizer:
  • Generates the classic OpenSSH ASCII art representation for instant visual fingerprint verification.
• Safe Auto-Save to ~/.ssh/:
  • Writes private key files with strict 0600 and public key files with 0644 file permissions.
  • Includes duplicate filename detection and explicit overwrite protection.

🗂️ Dedicated SSH Keys Workspace Tab (termlet://ssh-keys)

• Full Workspace Tab Experience:
  • Open and manage SSH keys in a dedicated workspace tab (SSHKeysView.tsx) featuring a key icon, tab persistence, and responsive split layout.
  • Quick launcher directly accessible from the bottom Status Bar (SSH Keys) and the Settings View.
• Local Keys Explorer (~/.ssh/):
  • Automatically scans and displays all local key pairs found in ~/.ssh/.
  • Shows algorithm badges, key comments, SHA256 fingerprints, file paths, and encryption status.
  • 1-click Copy Public Key to clipboard for pasting into GitHub, GitLab, or server configurations.
  • Safe key pair deletion with modal confirmation.

🚀 1-Click Remote Server Deployment (ssh-copy-id in-app)

• Direct Remote Authorization:
  • Install any generated or local public key onto any active SSH connection with a single click.
  • Automatically ensures remote ~/.ssh directory exists with 0700 permissions, appends the public key to ~/.ssh/authorized_keys, and enforces strict 0600 permissions.

🛠️ Connection Profile Integration

• In-Dialog Key Picker & Generator:
  • When configuring a private key connection in the Connection Profile Dialog (ConnectDialog.tsx), a "Pick / Generate Key..." button opens the manager and auto-populates the chosen or generated key path.
