fix: allow informational options before setup

[xuu33030]

Describe the PR

Fixes #47 by allowing --help, -h, --version, and -v to be handled before the configuration load and setup gate.

The CLI now normalizes the short informational aliases before passing them to yargs, while normal command execution continues to receive the configuration object. The entry point is also importable for focused regression tests without starting the CLI as a side effect.

Verification

• npm test
• npm run smoke in a clean clone with the patch applied
• Manual clean-environment checks for --help, -h, --version, and -v: all exit 0 without configuration files or setup prompts
• git diff --check

Notes

No documentation change is required; this restores standard informational CLI behavior.

For Altis Team Use

• Acceptance criteria met
• Automatic regression tests added
• Code changes follow existing project patterns
• Documentation updated (not required for this behavior)
• Module release created/scheduled (maintainer decision)
• Backport labels added (maintainer decision)

AI assistance was used during implementation; the change was locally reviewed and verified with the commands listed above.
