docs: link the Codeman app for Mac from the README and the wiki

The 1.50.0 release attaches Codeman.dmg to every release, so
https://github.com/Ark0N/Codeman/releases/latest/download/Codeman.dmg
always serves the newest app. This puts that link where a Mac user
looks first:

- README.md: one line under the install one-liner, and a short
  "On a Mac: the Codeman app" section in Quick Start, after Docker
  Compose. What the app does, the download, universal (Apple Silicon
  and Intel), macOS 11.3, the WebKit of Safari 16.4 for Codeman's page,
  macOS 15 (or a tmux already there) for the install from the app, and
  how to update it.
- README.zh-CN.md: the same, translated.
- docs/wiki/Installation.md: a matching section with a First launch
  list (the one "downloaded from the internet" question, the Local
  Network question on macOS 15) and the limits that matter on day one.
  Its anchors, #on-a-mac-the-codeman-app and #first-launch, are what
  the website links for first-launch help. Route A points to it.

The limits are copied from packages/desktop/README.md. The app is
signed with a Developer ID and notarized, so no Gatekeeper workaround
and no per-update Keychain prompt is described.

 The first run asks three questions (data folder, port, password; Enter takes the default, including a generated password), writes `docker/.env` for you, builds the image and ends on the URL once Codeman answers. The image already includes Claude Code, Codex, Gemini CLI and OpenCode. Codeman runs in a container and spawns Docker cases as sibling containers through the host socket. To update, use **App Settings → Updates**, or `git pull` and run the script again rather than a plain `docker compose up`, so the rebuilt image, refreshed volumes and entrypoint arrive together. See the [Docker deployment guide](docker/README.md) for Unraid, direct Compose commands, storage and networking options.
 
+### On a Mac: the Codeman app

+**[Download Codeman.dmg](https://github.com/Ark0N/Codeman/releases/latest/download/Codeman.dmg)** · one universal app for Apple Silicon and Intel · macOS 11.3 or later
+
+A small native app that opens Codeman in its own window. On a Mac without Codeman it installs it for you, with no Terminal and no administrator password, shows the install as a checklist, and offers to install a coding agent if the Mac has none yet. On a Mac that already runs Codeman it finds the server and opens it, or starts it when it is stopped. Under **Another machine** it connects to Codeman on your Mac mini, a home server or your tailnet, with the password kept in the Keychain, and can start an install over there through SSH. On a MacBook Pro whose Apple logo lights up, **View > Blink Apple Logo** blinks the logo by what your agents are doing, with a style of your own for working, for waiting for you and for needing permission; all three stay off until you choose. The app is Rust around macOS's own WebKit, not a bundled browser, so the download is under 5 MB.

+Open `Codeman.dmg`, drag Codeman into Applications and open it from there. macOS asks once whether to open an app downloaded from the internet: click **Open**.
+
+- **Quitting the app doesn't stop Codeman.** An install from the app runs Codeman as a LaunchAgent that starts at login, so your agents keep working with the window closed, and your browser and phone reach it as before.
+- **Codeman's page needs the WebKit of Safari 16.4.** The app starts on macOS 11.3, but Codeman itself needs macOS 13.3 or later, or macOS 11 or 12 with Safari 16.4 or later installed. On an older WebKit the app says so and does not connect.
+- **The install from the app needs macOS 15, or a tmux that is already there.** tmux comes from the tmux project's own builds, which need macOS 15. On an older Mac without tmux the app offers Terminal instead, where Homebrew installs it (that takes an administrator once).
+- **Updating.** The app doesn't update itself yet: download the new `Codeman.dmg` and drag it over the old copy.
