sshconfig-lint for VS Code

Semantic diagnostics for OpenSSH client configs. The extension uses the same Rust engine as the CLI and GitHub Action.

What it checks

• duplicate Host blocks and directives
• Host * ordering
• missing IdentityFile paths
• weak algorithms and unsafe options
• nested Include files and cycles
• unsafe ControlPath values

The matching release binary is downloaded once, verified with SHA256, and reused offline. No telemetry is collected. Set sshconfigLint.binaryPath when you prefer a system installation.

The extension recognizes .ssh/config, ssh_config, and dot_ssh/config. Add repository-specific paths with sshconfigLint.additionalFilePatterns.
