Improve Connection closed troubleshooting and setup guidance

[0xshitcode]

Summary

Fixes #14 by improving troubleshooting docs for Error: Connection closed, especially for Windows users who accidentally install the wrong npm package.

What changed

• docs/tutorials/getting-started.md
  • Added a dedicated Error: Connection closed troubleshooting section
  • Added explicit reset flow in a fresh directory
  • Clarified to install vibium (not clicker)
  • Added debug-log commands and AV exclusion note
• docs/tutorials/claude-code-mcp-setup.md
  • Added the same package-name clarification (vibium vs unrelated clicker)
  • Added debug-log guidance for Connection closed

Build/Test (GitHub Runner)

Ran on GitHub Actions runner:

• Build vibium binary
• Build JavaScript client
• Go tests (cd clicker && go test ./...)

Run: https://github.com/0xshitcode/vibium/actions/runs/22230289238

[hugs]

Thanks for putting this together! Unfortunately the docs have been restructured since this branch was created — claude-code-mcp-setup.md and getting-started.md no longer exist (now getting-started-mcp.md and getting-started-js.md).

We've also closed #14 with guidance on the root cause (install vibium not clicker, and allowlist vibium in your antivirus). Appreciate the contribution!
