SSH Key Support with Automatic SSH Agent Integration (OpenSSH / Pageant)

Request to add native SSH key management with automatic SSH agent integration. This would turn PearPass into a secure, unified hub for SSH authentication, handling key lifecycle safely in the system agent.

Proposed Features:

🔹 1. Entry-Level Key Management

• Attach private key files directly to vault entries.

• Auto-decrypt on agent load if the key is password-protected (use credentials from the entry).

• Display metadata: public key, fingerprints (MD5, SHA256), and key comment.

🔹 2. Lifecycle & Security Controls

• Add keys to the SSH agent automatically on vault unlock.

• Remove keys from the agent on vault lock/close.

• Optional "require confirmation" flag for key usage.

• Auto-remove timeout after last use (default: 600s, configurable).

🔹 3. UI

• Dedicated tab/window "Active SSH Keys" showing which keys are currently loaded in the agent.

• "Clear Agent" button to instantly remove all PearPass-managed keys.

🔹 4. Implementation Notes

• Integrate with the system OpenSSH agent (Win/Linux/macOS) and/or Pageant (PuTTY).

• Ensure compatibility with MobaXterm, WinSCP, PuTTY, native OpenSSH, VS Code Remote, etc.

• Keys must never be written to disk: operate exclusively in memory via the standard SSH agent protocol.

Benefits: ✅ Unified password & SSH key manager ✅ Enhanced security: keys reside only in memory, auto-expire, and clear on lock ✅ Seamless workflow with any terminal, IDE, or SSH client
