revert: restore pre-upstream-merge baseline (tree of 3b673150b)

Roll the tree back to the pre-merge tip 3b673150b, undoing the upstream sync merge 72f4f186d (303 files) and the 13 post-merge commits layered on top of it.

Purpose: restore the last pre-sync baseline so the reported OMEMO/OTR encryption regressions can be reproduced against a known-good state and the upstream sync ruled in or out as the cause. Nothing is dropped from history; the merge and every post-merge commit remain reachable and can be cherry-picked back selectively.

Baseline:     3b673150b chore(chatlog): disable background message file logging (stage 1)

Undoes merge: 72f4f186d merge: sync upstream profanity-im/profanity
