Add lightweight Ruflo wrapper fast paths for help and version commands

[JuicyBrandon]

Summary

Adds early exit handling in the Ruflo wrapper for lightweight smoke commands before importing the full @claude-flow/cli runtime.

Handled directly by the wrapper:

• ruflo --version
• ruflo -v
• ruflo --help
• ruflo -h
• ruflo mcp --help
• ruflo mcp -h

Why

The ruflo package is a thin wrapper around @claude-flow/cli. Currently, basic help and version checks can load the full Claude Flow runtime. In cold npx environments, this can make simple smoke checks slow, unreliable, or fail before the user receives basic CLI output.

This change keeps smoke commands lightweight and predictable while preserving full delegation for real command execution.

Validation

Tested in an isolated WSL lab clone.

Commands verified:

node ruflo/bin/ruflo.js --version
node ruflo/bin/ruflo.js -v
node ruflo/bin/ruflo.js --help
node ruflo/bin/ruflo.js -h
node ruflo/bin/ruflo.js mcp --help
node ruflo/bin/ruflo.js mcp -h
git diff --check

Results:

Version commands returned 3.10.3.
Help commands returned immediately.
MCP help returned immediately.
No MCP server was started.
No registration files were written.
git diff --check passed.

Scope

This does not change full Ruflo command execution. Runtime commands still delegate to @claude-flow/cli.

This only prevents basic smoke commands from loading the full runtime unnecessarily.
