// ParsePath normalizes the positional arguments of `lark-cli schema` into a
// slice of path segments. It accepts two equivalent forms:
//
//	lark-cli schema im.messages.reply  -> single arg, split on "."
//	lark-cli schema im messages reply  -> multiple args, used as-is
//	lark-cli schema "im chat.members bots" is NOT a supported form; quote
//	arguments individually if your shell needs it. Nested resources keep their
//	internal dots (e.g. "chat.members").
//
// Returns nil for zero args (bare invocation).
