1.6.2

Changed

• Code refactor; remove dead code, use verb prefixes for helpers, lockstep group invite Slack IDs
• Message and reaction sync skip Slack lookups until the channel has membership and publish targets
• File shares take the message ts from the upload response when present, then channel history
• Home tab reopen skips a rebuild when the content hash is unchanged
• User-token file shares keep the caption and Block Kit on the same native message as the file
• DEBUG logs include sync.* traces for message skip, pipeline fan-out, and file share ts

Fixed

• Pause Sync stops inbound until Resume
• User-token file shares skip inbound events by Slack file id and the share ts, so copies are not treated as new origins
• Reactions on a publishing Channel still fan out when the message is a synced copy; inbound creates stay skipped by echo and PostMeta
• Reactions and thread replies find existing messages by a six-decimal Slack ts, so older posts still match
• Thread replies Slack marks as a later share of a parent file still sync
• File-only bot shares record the share ts after Slack omits it on complete-upload, so thread replies still attach
