Greptile Summary

This PR renames the switch/sw command to checkout/ck in the CLI's help text, header comment, and error messages, and registers ck and checkout as new SHORT_CMDS aliases pointing to the existing switch handler. No logic changes are made; the sw and switch spellings continue to work at runtime.

• ck and checkout are added to SHORT_CMDS, both mapping to \"switch\", so the underlying handler is reused with no duplication.
• The help table, inline file-header comment, and the missing-argument error message are all updated to reference ck/checkout instead of sw/switch.
• The sw alias is silently removed from the help display but still resolves correctly at runtime, which could surprise existing users who look up the alias in help.

Confidence Score: 4/5

Safe to merge — no functional logic is changed and the new aliases route correctly to the existing handler.

The change is limited to alias mappings, display strings, and comment text. The new ck/checkout aliases correctly resolve to the switch case handler, and backward-compatible aliases (sw, switch) remain functional. The only notable gap is that sw is no longer mentioned in the help output even though it still works, which may silently confuse users who relied on it.

scripts/cli.ts — specifically the help table row for checkout and whether the sw alias should be noted for discoverability.

Important Files Changed

Filename	Overview
scripts/cli.ts	Help text, header comment, SHORT_CMDS mapping, and error/banner strings updated to surface checkout/ck as the primary command/alias, while the old sw alias is silently dropped from displayed help (though it still works at runtime).

### Issue 1 of 1
scripts/cli.ts:1043
The `sw` alias is silently dropped from the displayed help table. It still resolves at runtime (via `SHORT_CMDS`), so existing users or scripts that call `gg sw <branch>` keep working — but there's no indication in the help output that `sw` is still accepted. Adding it as a secondary note avoids surprising users who are familiar with the old alias.

```suggestion
    ["checkout <branch>", "ck <branch>", "git checkout <branch>  (sw alias still works)"],
