release: 0.1.4 «Eleuteriusz» — the list of commands lives in the chat now
Thirteen commands, and the only list of them was a README table nobody in a
Signal group can read — which had itself gone stale two releases earlier,
still advertising four commands after nine more had shipped. 0.1.1 gave each
command an output that says what the command is; that only helps once you
already know to type it.

!pomoc (also !pomocy, !help, !komendy, !commands) prints all fourteen,
grouped, one Polish line each.

The interesting part is that it cannot go stale. CommandRegistry.register now
takes the description as a REQUIRED argument, so a command that does not
explain itself does not compile; and render_help prints any command that
help_command.GROUPS forgot to file, under no heading, rather than dropping
it. Two independent ways to fail closed, because the README proved that a
hand-maintained second list is a list that drifts.

Command also gained `primary`, the first raw alias. The trigger set could not
supply it: those are folded skeletons in an unordered frozenset, so all that
survives of "!papież" there is "!papiez", and the styled Unicode aliases come
out as zalgo. aliases.json already lists the canonical Polish spelling first.

The full trigger table moves to DOCS-commands.md. It did not fit in README —
that file was already sitting exactly on the shared 250-line cap, and the
gate caught the overflow on the first commit attempt.

Exercised in testbot at the unbumped version before this bump: the live
dispatcher ran it and posted the list, journal clean. pytest 708 green at
100% branch coverage, e2e green including a new scenario that asserts !pomoc
mentions a command registered by a different module.
