Rune composability contract
Where v0.18.0 hardened the rune output contract, v0.19.0 builds on that stable base along several threads: visual polish of the Lumina theme, making rune composability a supported and validated surface (SPEC-084), turning bento into a proper composition substrate (SPEC-085), and improving the cross-page aggregation runes that the plan plugin leans on.
