feat(branding): rename fork to Nightcap and add AppImage release workflow

Show Nightcap as the app name in the desktop entry, window title,
dialogs, and metainfo. Binary, config paths, and desktop ID keep the
mocktail name. Publish Nightcap-x86_64.AppImage to GitHub Releases on
v* tags. README points at the fork's releases instead of upstream
packages.

Nightcap is a fork of [komaruworld/mocktail](https://github.com/komaruworld/mocktail)
with extra fixes for playing on a PC. The program, config paths, and desktop
entry keep the `mocktail` name so upstream fixes still apply cleanly.
- **Lower input lag.** Frames are shown as soon as they are ready instead of
waiting in a queue.

## Install
Grab the AppImage from the
[latest release](https://github.com/CoderDayton/nightcap/releases/latest),
make it executable, and run it:
```bash
chmod +x Nightcap-x86_64.AppImage
./Nightcap-x86_64.AppImage
```
Or build it from source using the steps under [Building](#building). For
Flatpak, AUR, DEB, and RPM packages of the unmodified upstream, see
[komaruworld/mocktail](https://github.com/komaruworld/mocktail#readme).
## How it works
```
@@ -44,73 +59,6 @@ The APK is checked before any native code is loaded. It is downloaded on first
launch and is not bundled with Mocktail. The last working copy is kept in case
an update fails.
## Install with Flatpak
Install the stable release from Flathub:
```bash
flatpak install flathub space.bigrat.mocktail
flatpak run space.bigrat.mocktail
```
Nightly builds are produced automatically from the latest `main` branch:
```bash
flatpak install --user https://mocktail.bigrat.space/mocktail.flatpakref
flatpak run space.bigrat.mocktail
```
## Install from the AUR
Arch Linux users can install either the pinned source release (`mocktail`) or
the current development version (`mocktail-git`) with an AUR helper:
```bash
paru -S mocktail-git
# or
yay -S mocktail-git
```
Use `mocktail` instead of `mocktail-git` to build the pinned release from
source, or install the stable prebuilt package with `paru -S mocktail-bin` or
`yay -S mocktail-bin`.
## Install with DNF
Fedora 44 users can install either the stable `mocktail` package or the
`mocktail-nightly` package built from `main`:
```bash
sudo curl -fsSL https://mocktail.bigrat.space/rpm/mocktail.repo \
-o /etc/yum.repos.d/mocktail.repo
sudo dnf install mocktail
# or
sudo dnf install mocktail-nightly
```
## Install with APT
Ubuntu 26.04 users can install either the stable `mocktail` package or the
`mocktail-nightly` package built from `main`:
```bash
sudo install -d -m 0755 /etc/apt/keyrings
sudo curl -fsSL https://mocktail.bigrat.space/mocktail-packages.gpg \
-o /etc/apt/keyrings/mocktail.gpg
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/mocktail.gpg] https://mocktail.bigrat.space/apt mocktail main" | \
