Update move command to accept standard mv args

[martinemde]

• I bumped the gem version (or don't need to) 💎

Aligns the bin/packs move command's argument order with the standard mv utility.

The command now accepts arguments as sources... destination (last argument is the destination pack), making it more intuitive and consistent with common CLI patterns.

@cursor Make sure sorbet passes:

Errors: 2

[cursor]

Fixed the Sorbet type errors by adding T.must() to assert non-nil values after the length check. Since we validate args.length >= 2 before destructuring, pack_name (the last element) and paths (all elements except the last) are guaranteed to exist.

The changes:

• Added T.must(pack_name) to ensure Sorbet knows pack_name is a String, not T.nilable(String)
• Added T.must(paths) to ensure Sorbet knows paths is a T::Array[String], not T.nilable(T::Array[String])

This satisfies Sorbet's type checker while preserving the logic. The linter shows no errors, and the type checks should pass in CI.
