chore: repo cleanup - pin actions, fix typos, improve gitignore

- build.yml: pin push-to-registry to SHA
- build-installer-iso.yml: pin checkout/upload-artifact to SHA,
  replace hardcoded registry with env vars, add env block
- Justfile: fix 'Virtal' typo (10x), fix shfmt error msg,
  quote $file in check/fix recipes
- .gitignore: add *.iso, *.qcow2, *.raw, .env, *.log
- iso/config.toml: remove leading space
- Containerfile: remove non-existent /tmp/build from cleanup
- build/50-prepare-flatpak-for-bazaar.sh: add executable permission
- build/README.md: update to reflect current script names

 # Build Scripts
 
-This directory contains build scripts that run during image creation. Scripts are executed in numerical order.
+This directory contains build scripts that run during image creation via bind mounts in the Containerfile.
 
 ## How It Works
 
-Scripts are named with a number prefix (e.g., `10-build.sh`, `20-onepassword.sh`) and run in ascending order during the container build process.
+Scripts are named with a number prefix and run in ascending order during the container build process. Each script is bind-mounted into the build container and executed individually.
 
 ## Included Scripts
 
-- **`10-build.sh`** - Main build script for base system modifications, package installation, and service configuration
+- **`10-repos.sh`** - RPM Fusion repositories einrichten (frei + nonfree)
+- **`20-multimedia.sh`** - Mesa Freeworld, Codecs, FFmpeg, GStreamer, Intel-Media-Treiber
+- **`30-virt.sh`** - Virtualisierung (libvirt, QEMU), Plasma-Setup, Distrobox, Micro, etc.
+- **`40-remove-packages.sh`** - Entfernt unerwuenschte Pakete (Firefox, Plasma Discover)
+- **`50-prepare-flatpak-for-bazaar.sh`** - Laedt Flathub-Repo-Definition fuer Bazaar
 
-## Example Scripts
+## Hilfsscript
 
-- **`20-onepassword.sh.example`** - Example showing how to install software from third-party RPM repositories (Google Chrome, 1Password)
+- **`copr-helpers.sh`** - Funktionen fuer sichere COPR-Repo-Installation (enable, install, disable)
 
-To use an example script:
+## Erstellung eigener Scripts
-1. Remove the `.example` extension
-2. Make it executable: `chmod +x build/20-yourscript.sh`
-3. The build system will automatically run it in numerical order
-
-## Creating Your Own Scripts
-
-Create numbered scripts for different purposes:
 
 ```bash
-# 10-build.sh - Base system (already exists)
+# Neues Script mit nummeriertem Prefix erstellen
-# 20-drivers.sh - Hardware drivers  
+# Die Number bestimmt die Ausfuehrungsreihenfolge
-# 30-development.sh - Development tools
-# 40-gaming.sh - Gaming software
-# 50-cleanup.sh - Final cleanup tasks
-```
 
-### Script Template
+#!/usr/bin/bash
+set -eoux pipefail
 
-```bash
+echo "Installiere Pakete..."
-#!/usr/bin/env bash
+dnf5 install -y --allowerasing some-package
-set -oue pipefail
-
-echo "Running custom setup..."
-# Your commands here
 ```
 
 ### Best Practices
 
-- **Use descriptive names**: `20-nvidia-drivers.sh` is better than `20-stuff.sh`
+- **Beschreibende Namen**: `25-nvidia.sh` statt `25-stuff.sh`
-- **One purpose per script**: Easier to debug and maintain
+- **Ein Script pro Zweck**: Einfacher zu debuggen und zu warten
-- **Clean up after yourself**: Remove temporary files and disable temporary repos
+- **Aufraeumen**: Temporaere Dateien entfernen, temporaere Repos deaktivieren
-- **Test incrementally**: Add one script at a time and test builds
+- **Inkrementell testen**: Ein Script nach dem anderen hinzufuegen
-- **Comment your code**: Future you will thank present you
+- **Kommentare**: Das zukuenftige Ich wird es schaetzen
 
-### Disabling Scripts
+### Script deaktivieren
 
-To temporarily disable a script without deleting it:
+Ohne Loeschen deaktivieren:
-- Rename it with `.disabled` extension: `20-script.sh.disabled`
+- Umbenennen: `20-script.sh` → `20-script.sh.disabled`
-- Or remove execute permission: `chmod -x build/20-script.sh`
+- Execute-Recht entfernen: `chmod -x build/20-script.sh`
 
-## Execution Order
+## Ausfuehrung im Containerfile
-
-The Containerfile runs scripts like this:
 
 ```dockerfile
-RUN /ctx/build/10-build.sh
+RUN --mount=type=bind,from=ctx,source=/build/10-repos.sh,target=/tmp/10-repos.sh \
+    --mount=type=cache,dst=/var/cache \
+    --mount=type=tmpfs,dst=/tmp \
+    bash /tmp/10-repos.sh && dnf5 clean all
 ```
 
-If you want to run multiple scripts, you can:
+## Hinweise
 
-1. **Modify Containerfile** to run each script explicitly
+- Scripts laufen als root waehrend des Builds
-2. **Create a runner script** that executes all numbered scripts
+- Build-Kontext ist ueber Bind-Mounts verfuegbar
-3. **Use the default** and keep everything in `10-build.sh` (simplest)
+- Nutze `dnf5` fuer Paketverwaltung (nicht dnf oder yum)
-
+- Immer `-y` Flag fuer nicht-interaktive Installationen verwenden
-## Notes
+- Cache-Mounts (`--mount=type=cache`) verhindern Neudownload bei Aenderungen
-
-- Scripts run as root during build
-- Build context is available at `/ctx`
-- Use dnf5 for package management (not dnf or yum)
-- Always use `-y` flag for non-interactive installs
