A UI pass: prompts that tell the truth, and a HUD that does not collide

Prompts named the default keys whatever was bound. Every action is
rebindable, but the HUD said "WASD move", "LMB fire", "hold F" and "1-4
use", the quartermaster said "E talk" and the upgrade screen "Close (E)".
All of them now go through Settings.short_label(), and a test rebinds
fire, escape, interact and a slot key and checks each prompt follows.

The HUD's top-left was a developer's status line -- name, instance id,
health as text, frame rate -- with the boss bar drawn over its right end
and the level-up notice sharing a row with the escape bar. It is now
name and level, where you are, health with its numbers, experience,
escape and level-ups, stacked by a running cursor so nothing has a fixed
row to collide on. Instance and fps moved behind F1, which is who they
were for. Arrival protection is a centred banner rather than a note
beside the health bar, because it is the one moment the rules change.

A hit used to tint the whole screen red, which in a bullet hell dims the
bullets at exactly the moment you are among them. It is an edge now, and
the same edge pulses below a third of your health. New: a message feed
above the inventory for what the server just confirmed -- items taken,
used and dropped, levels gained -- and party health top-right in a
dungeon, where the hub shows who is online. The pickup prompt now also
names the dungeon under your feet when you stand on its ring, in the
same order the server resolves that key: loot first, then the entrance.

The boss bar used to announce the boss to anyone within the actor
interest radius -- which passes through walls -- so a player in the
entrance room was told the Warden was near. It waits until the fog has
actually lit the boss once, then stays for the fight.

Permadeath was announced only by the roster screen appearing. The client
records its own death from the server's event and the roster says who
fell, at what level, and where. The connect screen lost a name field
that did nothing for a person -- it only named the characters bots
create -- gained a proper panel, remembers the last server, and shows
the protocol number a mismatch refusal will quote.

And screenshot.tscn ran as the player's real account against their real
character store, walking their character into dungeons for pictures --
with health now carried between runs, a stray hit would have stuck. It
has its own store and account now, like every diagnostic, and a seeded
character. The real store was checked: nothing it carries changed.
