chore: release 26.5-alpha
Rolls the HTTPS handshake fix (#10) and the README realignment into a
tagged release. Also closes the 26.4 follow-up that the wizard footer
version was hand-pinned: webinstaller/app.py now resolves the version
via a Flask context processor (reads /opt/furtka/VERSION on the live
ISO, written by iso/build.sh from pyproject.toml at build time; falls
back to pyproject.toml in dev runs, then to "dev"). pyproject.toml and
the website version strings bumped in the same commit so every surface
reports 26.5-alpha consistently.
