- layoutTextItem now sizes a text item to the true font line height (A + D)
instead of the cap box: the line stack starts at lineBoxTopInset (the
ascender headroom, max(0, fontAscent - fontLineHeight)) and the returned
height is padded by the last line's descender. Inter-line advance is
unchanged and per-line frames stay the cap box, so the baseline draw,
decorations, reveal mask, and inline attachments translate consistently;
the page grows.
- Size inline custom emoji to ~the font line height
(font.ascender - font.descender + 4*pointSize/17) so they fit the taller
line box instead of overflowing it; the line is not inflated.
- Add a dedicated code-block text style for rich messages (monospace font +
codeBlock theme attribute) threaded through the rich-data bubble and send
preview; unify the bubble code-block/separator colors.
- Adjust inter-block spacings and assorted V2 layout/divider details.
- Document the true-font-height box and emoji sizing in CLAUDE.md.

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.
