In `@README.md`:
- Around line 85-86: The README sentence about Arch Linux packages is ambiguous
about whether the `arch` namespace is required; update the wording around "Arch
Linux packages use a namespace prefix: `pkg:alpm/arch/pacman` for official
repos, `pkg:alpm/aur/paru` for AUR." and the following sentence so it clearly
states that official Arch packages may omit the `arch` namespace (it defaults to
`arch` when omitted) while AUR packages must include the explicit `aur`
namespace; rephrase both sentences to convey that distinction unambiguously.
