Collapse the edition split — one target, twins merged, verify-editions retired

Phase 1 of the 2026-07-30 one-app pivot (DESIGN 0bec9a6, card c3a3ddd5):
the KanbanPro target, LaneworkPro scheme, KanbanProTests module-alias
bundle, KanbanPro/ source root and scripts/verify-editions.sh retire
wholesale. project.yml reads as a single-target file again (anchors
inlined, header rewritten in tier vocabulary).

The edition twins merge: EditionTypes -> PasteboardTypes (one
UTType(exportedAs:) home — the one app owns the family types),
EditionAbout -> AboutBox (the quiet Pro signpost survives as the About
box's one line; "…in Settings" deferred until the StoreKit phase gives
it somewhere to point). InertGitTests drops its Base prefix — the
inert-.git posture is unconditional app behavior, unsubscribed and
lapsed being one state.

Entitlements gain com.apple.security.network.client, declared now and
dormant until Pro's remotes use it; no keychain access group. The App
Group key deliberately stays — it goes with AppGroup.swift in phase 2,
since pulling it first would silently drop the app into the fallback
container. README/RELEASE.md build-and-pipeline prose updated to the
one-record world; the subscription story lands with phase 3.

1893 tests in 322 suites green.
