change: migrate SSH integration from standalone option to shell-integration-features flags

- Add ssh_env and ssh_terminfo flags to ShellIntegrationFeatures
- Remove SSHIntegration enum and ssh-integration config option
- Update setupFeatures to handle new flags via reflection
- Remove setupSSHIntegration function and all references

Integrates SSH functionality into existing shell-integration-features
system for better consistency and user control.

-/// Allowable values are:

-///   * `off` - No SSH integration, use standard ssh binary.
