`-help` autocomplete suggests an invalid flag and crashes the CLI

What happened?

Summary

Flag autocompletion suggests -help (single dash), which isn't a valid flag. Accepting it and pressing Enter throws an error and exits the CLI. Only --help (double dash) works.

Steps to reproduce

1. Start typing a flag with -
2. The CLI suggests/autocompletes -help
3. Press TAB → completes to -help
4. Press Enter → error is shown and the CLI closes

Actual behavior

• -help is suggested but is invalid
• Running -help errors out and terminates the CLI session
• Typing help (no dashes) immediately starts a browser session
• Only --help works correctly

Expected behavior

• Autocomplete should suggest valid default flags (e.g. --help), not -help
• Invalid input should show a graceful usage/help message instead of crashing the CLI

Environment

• OS: macOS
• Kane CLI version: not captured

Thanks for the report. To clarify what's happening here:

The supported help invocations

kane-cli follows the standard POSIX/GNU convention used by virtually every CLI:

• kane-cli --help (long form)
• kane-cli -h (short form)
• kane-cli help (subcommand form)

This is the generic, expected way flags work across CLI tools. There is no -help (single dash + word) flag because that's not a valid form in this convention — -help would be parsed as
the short flags -h -e -l -p.

About the -help autocomplete

The -help suggestion you're seeing is generated by your shell's tab-completion (zsh/bash on macOS), not by kane-cli. Shells produce generic guesses for unknown commands. kane-cli does
not ship a shell-completion script, and providing/altering terminal autocomplete is a shell-level feature — not something the CLI itself controls.
When -help (or any unknown flag) is entered, Commander correctly rejects it and exits — that's standard CLI behavior.

We will add better feedback for unkown commands @anmolg-LT
