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.

Add the RichText.textSpoiler case end-to-end: model + Postbox coding,
FlatBuffers schema/codec, and Api.RichText parsing/serialization (lossless).
Display attaches the spoiler attribute, collects per-line spoiler rects in
the V2 layout, clips obscured glyphs and draws an energy-gated dust overlay
in the V2 text view, propagates the reveal flag across the nested V2 tree
(building dust for freshly-created text views), and wires tap-to-reveal
routing in the rich-data bubble.
Also seeds the streaming reveal cursor across chunk rebuilds and refines
status date positioning.

Implement the nine message-entity RichText cases (textMention,
textMentionName, textHashtag, textCashtag, textBotCommand, textBankCard,
textAutoUrl, textAutoEmail, textAutoPhone): model + Postbox coding,
FlatBuffers schema/codec, Api.RichText parsing/serialization (lossless),
InstantPage display attaching the matching TelegramTextAttributes keys, and
tap routing in the rich-data bubble mirroring ChatMessageTextBubbleContentNode.
mentionName display resolves via EnginePeer.Id (PeerId not in scope).
Also lets rich-data text selection reach a line's trailing edge and fixes
the date/status node positioning to match TextBubble.

Add the RichText.textCustomEmoji(fileId:alt:) case end-to-end: model +
Postbox coding, FlatBuffers schema/codec, and Api.RichText
parsing/serialization (lossless), plus display in the InstantPage V2
renderer. The emoji renders as an InlineStickerItemLayer that participates
in the streaming reveal (pops in as the reveal cursor crosses it) and is
gated by the bubble's visibility rect, propagated recursively through the
nested V2 view tree. Also frees the CTRunDelegate extent buffers for the
image/formula/custom-emoji attachment arms and documents the feature in
CLAUDE.md.
