Add CUB implementation plan spec and update project documentation

Browse Source 
New docs/_CUB_RBPKGBUILD_IMPL_PLAN.md with full CUB package builder specification
covering RBPKGBUILD format, CLI commands, build flow, BUR repository, and AUR conversion.
Updated AGENTS.md with pkgutils extensions and CUB integration details.
Updated AMD GPU integration docs with current P2 progress.

IVRS and MCFG were previously listed as "implemented" but the stubs were broken. They have
been removed from acpid. IVRS needs a real AMD IOMMU driver (P2+ scope). MCFG is better
handled by pcid discovering PCIe config space directly.
