03-configuration schedules work 'in a later phase'; itd-2609211913453478 retired phases as the unit of sequencing.

A terminology drift (severity nitpick) found by the cross-document consistency pass.

• End A: .abcd/development/brief/05-internals/03-configuration.md:428 — "Schema versioning and cross-version migration come in a later phase"
• End B: .abcd/development/intents/shipped/itd-2609211913453478-one-page-in-the-glossary-maps-abcd-s.md:55 — "Phases and milestones are retired; sequencing is dependencies plus the lifecycle shelves"

itd-2609211913453478 rules that phases and milestones are retired and that sequencing is dependencies plus the lifecycle shelves. 03-configuration still says schema versioning and migration come in a later phase, that migrators are added if a later phase changes the shape, that scheduled sync comes in a later phase, and that cross-project memory pages are a later phase. It uses the retired unit as if it still sequences work.
