Add the wiki, Quality and Release workflows

Add a wiki/ folder with a .publish marker for the shared Publish wiki
workflow, a Quality workflow (shellcheck and shfmt through the shared
reusable workflow) and a manual Release workflow that builds the release
page from CHANGELOG.md.

Set switch_case_indent for *.sh in .editorconfig so shfmt accepts the
existing case layout.

+# Getting started
+
+## Requirements
+
+| Tool | Needed for |
+| --- | --- |
+| bash 4.4 or later | the script (macOS ships 3.2: install a newer bash first) |
+| `git` | the local project and the framework submodule |
+| `curl` | the GitHub and Gitea APIs |
+| `ssh` (optional) | the SSH check; without it the framework steps are skipped |
+| `jq` (optional) | JSON parsing; without it a small built-in reader is used |
+
+## Install
+
+```bash
+git clone https://git.tirsystem.com/TirSystem-BashScript/RepoFoundry.git
+cd RepoFoundry
+src/create-project.sh --help
+```
+
+Nothing is installed system-wide: the script runs from the checkout.
+
+## Configure
+
+Copy `config.env.example` to `config.env` and `.env.example` to `.env`, then set the service addresses and the tokens (see [SSH and tokens](SSH-and-tokens)). `.env` holds credentials and is never committed.
+
+## Run
+
+Start the script from the folder that should hold the new project:
+
+```bash
+src/create-project.sh            # dry run: reads from the hosts, creates nothing
+src/create-project.sh --apply    # creates everything after a final yes
+```
+
+No commit is made in the new project. Work on a branch there: the framework's hooks refuse commits on `main`.
