+Close the entry-nameability invariant on the four remaining public entries that leaked it (#12414). Generalizing #11350/#11709's `defineStack`-only probe to every public entry found the class was never fully closed: seven (entry, type) pairs across four entries still had a `define*` factory's return type expand to mention a type the entry itself did not re-export — `Book`, `FormField`, `NavigationItem` from the root `@objectstack/spec` entry, `UnknownAuthoringKeyFinding` from `@objectstack/spec/kernel`, `FilterCondition` and `StateNodeConfig` from `@objectstack/spec/ai`, and `FilterCondition` from `@objectstack/spec/ui`. Each is repaired the same way as the prior two rounds: one re-export line on the leaking entry, from the module that already declares the type as public on its own subpath. A consumer writing an un-annotated `export const x = defineBook(...)` (or the `/ui`, `/ai`, `/kernel` equivalent) previously hit TS2883 naming an unaddressable hash-named internal dist chunk and could not build; all seven now declaration-emit cleanly with no annotation required. No runtime change. `packages/spec/entry-nameability.baseline.json`, the shrink-only ledger `check:entry-nameability` (#11986) reads, is now empty — the class it was tracking is closed.
