saturnus 0.10.3 fixes what two code reviews found: quitting the desktop app
now saves, and failed writes, backups and directory changes clean up after
themselves.

Get it
- On the web, nothing to install: https://ractive.ch/saturnus/app/
(Chrome or Edge for a serial cable; every browser for the emulated
calculator).
- The desktop app saturnus_0.10.3_… (on Linux saturnus-app), with
a -SHA256SUMS file beside them:
- macOS, Apple silicon: .dmg, signed and notarised, or brew trust --cask ractive/tap/saturnus-app once, then brew install --cask ractive/tap/saturnus-app;
- Windows: .msi or -setup.exe for x86_64 (x64) and ARM (arm64);
- Linux: .deb, .rpm or .AppImage for x86_64 (amd64, x86_64)
and ARM (arm64, aarch64). Add yourself to the dialout group to
use a serial port.
- The command-line tools saturnus and satx: cargo install,
Homebrew ractive/tap, Scoop ractive, or the archives and Linux
packages below.
- Libraries on crates.io, all at 0.10.3.

Desktop app and web page
- Quitting the desktop app saves the calculator. Cmd+Q on a Mac now
saves an unsaved change, as closing the window always did.
- A fresh start keeps what it should. A ROM that doesn't boot no longer
deletes the kept state. A ROM that boots as another model reads or clears
that model's state, not the one you asked for.
- A failed save leaves the old file. The desktop app writes saved files
and its AI access setting to the side, then moves them into place.

satx and Files
- A variable name with @ is refused. The calculator reads @ as the
start of a comment, so satx and Files no longer take such a name.
- A directory that isn't there changes nothing. satx --dir, satx ls PATH and the REPL's :cd and :ls leave the calculator where it was
when a name in the path is missing, not part of the way down it.
satx xserv goes back to HOME, as XSERV can't say where it was.
- A backup that fails no longer leaves its copies behind. satx backup
and Files remove the copy in port 0 when the calculator runs out of
memory, and a backup of an emulated calculator whose server stops
answering removes what it made. A port copy it can't be sure of stays,
and the error says so.
- Files replaces a variable with a long name. The swap goes out as three
commands when it doesn't fit in one packet. A name too long even for that
is refused, and the old variable stays.
- satx get --force replaces a file whole. A failed write leaves the
old file, and a new file it could not finish is removed. In a directory
where satx can't create a file, --force still writes in place, so a
failed write there loses the old content.
- Smaller fixes. satx rm X X deletes X once instead of failing on the
second. satx repl --json sends nothing more once its reader has closed.

Emulator
- A transfer that fails lets go of a key it held down.
- A UART break that is looped back and let go early leaves the receiver
idle (inferred: the manual covers a full break only).
