fix: preserve URL query strings in invoke output

[dprevoznik]

Summary

• Fixes pretty-printed kernel invoke output escaping & as \\u0026 (and similarly <, >), which breaks copy/paste of URLs returned in invocation output (e.g. replay URLs).
• Switches JSON pretty-printing to a custom encoder with SetEscapeHTML(false).

Why

Go's default json.MarshalIndent escapes HTML-sensitive characters. When the CLI re-marshals invocation output for pretty printing, URLs like ...?jwt=...&replay_id=... can show up as ...?jwt=...\\u0026replay_id=....

Test plan

• go test ./...

---

Note

Prevents HTML character escaping in pretty-printed invoke results by using a custom JSON encoder to preserve URL characters.

• CLI – cmd/invoke.go:
  • Use custom JSON encoder for printResult with SetEscapeHTML(false) and indentation to avoid escaping &, <, > in pretty-printed output; trims trailing newline.

Example of running locally with the fix:

/Users/dprevoznik/Documents/GitHub/cli/bin/kernel invoke python-openagi-cua openagi-default-task -p '{"instruction": "Navigate to https://agiopen.org and click the What is Computer Use? button", "record_replay": "True"}'

And the result with the correct replay URL:
