Feat/cs/jumbomoji

[ReagentX]

• Refactor BubbleComponent → Run(Vec<AttributedRange>)
  • Models the parsed typedstream more faithfully
    • Attribute runs are grouped by __kIMMessagePartAttributeName
    • Each range carries its effects, optional inline attachment, and the emoji_image hint
• Inline stickers (Jumbomoji)
  • Resolves Support Jumbomoji #755 and Support inline stickers as emoji images #756
  • Memoji/genmoji/custom stickers render inline as glyph-sized <img>s, classified by Apple's MIME-independent emoji_image hint, with jumbo/medium/normal sizing by glyph count
  • In edited & translated messages:
    • Translated messages preserve text + translation + sticker
    • Orphaned attachment placeholders stripped from the translation
    • TXT surfaces translations for sticker-bearing runs
• GUID-based attachment resolution
  • AttachmentResolver binds body placeholders to rows by file-transfer GUID (positional fallback for legacy bodies), fixing multi-attachment ordering
  • Add guid field to Attachment struct
• Attachment-handling fixes
  • The "encoding" label is gated to the modes that actually transcode (image stickers in Basic/Full, video in Full)
  • A missing/dangling inline attachment now renders a placeholder instead of silently vanishing.
• crabstep migration
  • adapted to the lazy PropertyGroup API
  • Depends on Feat/cs/perf++ crabstep#17
• Performance enhancements
  • SQLite read-path mmap/cache PRAGMAs + bulk streaming blob reads
• Tests & fixtures
  • Adds parse and render coverage for every inline-sticker shape:
    • Memoji/Genmoji/custom
    • Animated (block) vs static
    • Multi-inline ordering
    • Edited
    • Translated

Pull request overview

Refactors BubbleComponent from separate Text/Attachment variants into a unified Run(Vec<AttributedRange>) to faithfully model the underlying NSAttributedString, then leverages this to add inline-sticker (Jumbomoji/Memoji/Genmoji) rendering, GUID-based attachment resolution, and several performance/correctness fixes.

Changes:

• Replace BubbleComponent::Text/Attachment with Run(Vec<AttributedRange>) grouped by __kIMMessagePartAttributeName; each range carries effects, optional AttachmentMeta, and an emoji_image hint.
• Implement inline-sticker rendering (HTML) with jumbomoji sizing (1/2-3/4+ glyphs → jumbo/medium/normal); preserve text + translation + sticker in translated/edited paths; strip orphaned \u{FFFC} placeholders from translations.
• Add AttachmentResolver (GUID-first, positional fallback) and Attachment.guid field to fix multi-attachment ordering; migrate to crabstep 0.4.0 lazy API; add SQLite mmap_size/cache_size PRAGMAs and bulk blob reads.
