v3.12.6

v3.12.6 — Linux GUI keyboard fix, wider Linux compatibility, release-pipeline hardening

GUI (Linux)

• FIXED: the GUI crashed (segfault) on the first key press on some
  distributions. The binary bundled half of the libxkbcommon library pair;
  the GUI now always uses the host's matched pair (and CI installs both
  halves as belt-and-braces), eliminating the crash in
  xkb_state_key_get_layout.
• A saved SSH port 0 is no longer silently rewritten to 22 at connect
  time.

Compatibility

• Linux binaries are now built against glibc 2.35 — they run on
  RHEL/Rocky/AlmaLinux 9, Debian 12 and other distributions that the
  previous builds refused to start on (GLIBC_2.38 not found).

Release pipeline (Windows NTFS ACL support)

• CI now verifies pywin32 both in the build environment and inside the
  frozen .exe — a release can no longer ship a Windows binary whose NTFS
  owner/DACL preservation silently no-ops.
• pywin32 installs from the tracked requirements-win.txt everywhere (one
  source of truth for the version pin); removed the ineffective
  --collect-submodules=win32.
