Add a first-class `checked: Bool?` to InstantPageListItem (orthogonal to the ordered-list `num`), replacing the prior sentinel-string-in-num prototype. - Data model: enum third associated value on .text/.blocks; Postbox + a new FlatBuffers `checkState` tri-state field (0=nil,1=unchecked,2=checked, backward-compatible); Equatable. - Transmission: read/write the native API `checkbox`=flags.0 / `checked`=flags.1 bits on all four PageListItem / PageListOrderedItem constructors, so checkbox state survives the server round-trip for sender and recipients. - Markdown: forward parser routes detected `[ ]`/`[x]` into `checked` (keeping the real number for ordered items); reverse converter emits `- [ ]`/`- [x]` so editing a rich message round-trips. - Display: V1 + V2 layout detect via `item.checked`; the V2 renderer draws real CheckNode artwork (was a placeholder); preview text shows a checkbox glyph instead of leaking the old sentinel.
