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

-0.17.0 (2026-03-26)
-===================
-
-Special thanks to our sponsor Matthew Fennell!
-
-3 people contributed to this release: @botantony, @sjaeckel and @jubalh.
-
-The last release (0.16.0) was the first that could be compiled with the Meson build system.
-It provided a tarball for autotools and a separate one for meson. The autotools tarball was done
-so that distributions don't need dependencies on automake, autoconf and libtool.
-
-Several distributions are dropping vendor tarballs and use git checkouts or autogenerated tarballs nowadays.
-Meaning they need to run the above mentioned tools in the case of the autotools build anyways.
-
-So this release will only be shipped with tarballs generated with meson. Profanity can still be compiled with both autotools or meson for easier adjustments. Autotols users just need to generate configure first. The next release will only use Meson. So we encourage everybody to build with Meson arleady and report any bugs they encounter.
-
-We finally re-enabled functional tests (along with our existing unit tests) again!
-It would be appreciated if we could find people who want to help us expand the unit and functional tests so we are less likely to introduce regressions when we rewrite existing code.
