Refine setup workflows and add architecture map

- Split virgin tests into separate root and user GitHub Actions workflows
  (test-virgin-root, test-virgin-user) and adjust Arch container flows
- Introduce scripts/installation/venv-create.sh and reuse it from
  scripts/installation/main.sh with separate root/system and user/dev paths
- Add PKGMGR architecture & setup map (assets/map.png) and section in README
  with link to the up-to-date master page
- Simplify README by removing outdated Docker quickstart, usage examples,
  and AI footer
- Extend .gitignore to exclude src/source artifacts

 ## Installation ⚙️
 
@@ -51,55 +60,6 @@ The `make setup` command will:
 - Install required packages from `requirements.txt`.
 - Execute `python main.py install` to complete the installation.
 
-## Docker Quickstart 🐳
-
-Alternatively to installing locally, you can use Docker: build the image with
-
-```bash
-docker build --no-cache -t pkgmgr .
-```
-
-or alternativ pull it via
-
-```bash
-docker pull kevinveenbirkenbach/pkgmgr:latest
-```
-
-and then run
-
-```bash
-docker run --rm pkgmgr --help
-```
-
-## Usage 📖
-
-Run the script with different commands. For example:
-
-- **Install all packages:**
-  ```bash
-  pkgmgr install --all
-  ```
-- **Pull updates for a specific repository:**
-  ```bash
-  pkgmgr pull pkgmgr
-  ```
-- **Commit changes with extra Git parameters:**
-  ```bash
-  pkgmgr commit pkgmgr -- -m "Your commit message"
-  ```
-- **List all configured packages:**
-  ```bash
-  pkgmgr config show
-  ```
-- **Manage configuration:**
-  ```bash
-  pkgmgr config init
-  pkgmgr config add
-  pkgmgr config edit
-  pkgmgr config delete <identifier>
-  pkgmgr config ignore <identifier> --set true
-  ```
