Bug: Missing shebang in CLI binary and Security Research Disclosure

Describe the bug

1. CLI Functional Bug

I noticed that the CLI binary in @stacksjs/tlsx v0.13.0 is missing the shebang line (#!/usr/bin/env node) at the top of bin/cli.js. On macOS and Linux, this causes the terminal to execute the file as a Shell script instead of a Node.js script, leading to a syntax error: syntax error near unexpected token 's'. Suggested Fix: Add #!/usr/bin/env node to the first line of the CLI source.

2. Security Disclosure

While debugging the issue above, I performed a security audit of the codebase and identified a critical command injection vulnerability (RCE). Please contact dr3m19@icloud.com for more details.
