Sweep 14 BUILD files whose modules no longer have any source file with
`import Postbox`. All targets are ChatMessage*BubbleContentNode subclasses
plus WallpaperPreviewMedia — modules whose Swift sources stopped importing
Postbox in earlier waves but whose BUILD deps were not cleaned up.
Pre-flight: for each `BUILD` containing `"//submodules/Postbox"`, verified
no source file under `<module>/Sources` matches `^import Postbox$`. 14
modules met the criterion.
Build: 15s warm-cache verify, 0 errors.
Modules:
- ChatMessageActionBubbleContentNode
- ChatMessageEventLogPreviousDescriptionContentNode
- ChatMessageEventLogPreviousLinkContentNode
- ChatMessageEventLogPreviousMessageContentNode
- ChatMessageFileBubbleContentNode
- ChatMessageGameBubbleContentNode
- ChatMessageInvoiceBubbleContentNode
- ChatMessageMapBubbleContentNode
- ChatMessageMediaBubbleContentNode
- ChatMessageProfilePhotoSuggestionContentNode
- ChatMessageStoryMentionContentNode
- ChatMessageWallpaperBubbleContentNode
- ChatMessageWebpageBubbleContentNode
- WallpaperPreviewMedia
Pre-wave attempt failure note: tried 5 source-side `import Postbox` drops
first (StatsMessageItem, StarsAvatarComponent, PeerListItemComponent,
WebAppMessagePreviewScreen, OpenChatMessage). All 5 hit hidden bare
`Media`/`Message`/`PeerStoryStats`/`areMediaArraysEqual` references that
the prior pre-flight regex missed. Reverted source edits; only the
risk-free BUILD-dep sweep survives in this commit.
Lesson: pre-flight regex MUST include bare Postbox protocols
`\bMedia\b`, `\bMessage\b`, `\bPeer\b`, plus the Postbox helper
`areMediaArraysEqual` and the `PeerStoryStats` type. The previous
identifier-typealias-only regex was insufficient.
