fix: bring the docs in line with the no-admin route (release review)

Name the real trigger and CODEMAN_NO_ADMIN=0 in the READMEs and the
Installation page, add the install without git to the update tables and the
updater notes, record the installer's downloads in the supply chain section,
and say that the data directory question also removes a kept runtime.

 - **How it's reachable, your choice.** **Tailscale** (loopback bind fronted by `tailscale serve`, so you get `https://<machine>.<tailnet>.ts.net` with a real certificate and your tailnet as the login, no password needed), **any device on your network** (`0.0.0.0`, with a strongly recommended password prompt), or **this machine only** (`127.0.0.1`, safest). Skipping the password on a network bind requires an explicit confirmation and ends with a loud warning. The highlighted default reflects what is already on the machine (Tailscale when it is already connected, your existing binding on a re-run), and a bare Enter never pulls in new software. If another app already owns `:443` on your node, Codeman goes under `https://<machine>.<tailnet>.ts.net/codeman` or on a second port instead of replacing it. A bare `codeman web` started by hand still defaults to loopback.
 - **The name is yours to choose.** By default the URL uses the machine's existing tailnet name. Answering yes to the second question renames the machine to `codeman-<hostname>` (which also renames it for SSH, so the default is no); `install.sh name` does it later.
 - **Re-run to update.** The same one-liner updates a finished install in place: local changes in `~/.codeman/app` are stashed (never discarded), and a running service is restarted and verified. If a first install was interrupted, re-running resumes the full setup instead. `install.sh status` prints the URLs and the QR code again; `install.sh update`, `install.sh tailscale` and `install.sh uninstall` also exist.
-- **No administrator rights needed.** On an account without `sudo` (or a Mac account that is not an administrator), the installer downloads Node.js from nodejs.org and the tmux project's own build into `~/.codeman/runtime`, each checked against its SHA-256, and takes the source as an archive when there is no working git. `--no-admin` forces that route. Two limits: Linux needs make, a C++ compiler and python3 to be there already, and the tmux download needs macOS 15 or newer. Details in the [wiki](https://github.com/Ark0N/Codeman/wiki/Installation#without-administrator-rights).

 - **Flags for the impatient.** `curl -fsSL https://getcodeman.com/install | bash -s -- --tailscale --service` answers the questions from the command line (`--lan`, `--local`, `--run`, `--no-start`, `--name <n>`, `--port <n>`, `--yes` too). **CI / headless:** without a terminal attached, steps that would change your system abort with instructions instead of running silently; set `CODEMAN_NONINTERACTIVE=1` to approve them for automation.

The installer detects whichever of the ten is present; if none is found, it offers to install any of them from a menu (DeepSeek excepted, since its npm package installs only a launcher with no runnable profile), or you can skip and install one yourself later.

 - **怎么访问，由你决定。** 安装器提供三种到达仪表盘的方式：**Tailscale**（环回绑定，由 `tailscale serve` 代理，得到带真实证书的 `https://<机器名>.<tailnet>.ts.net`，用你的 tailnet 当登录，无需密码）、**局域网内任意设备**（`0.0.0.0`，会提示设置一个强烈推荐的密码），或**仅本机**（`127.0.0.1`，最安全）。绑定网络却跳过密码需要显式确认，并以醒目警告收尾。高亮的默认项反映机器上已有的状态（已在用 Tailscale 时默认 Tailscale，重跑时沿用现有绑定），直接回车绝不会引入新软件。如果你节点上的 `:443` 已被别的应用占用，Codeman 会改用 `https://<机器名>.<tailnet>.ts.net/codeman` 或第二个端口，而不是把它替换掉。手动运行的 `codeman web` 仍默认仅环回。
 - **名字由你来定。** 默认情况下，URL 用的是这台机器在 tailnet 里现有的名字。第二个问题答「是」会把机器改名为 `codeman-<hostname>`（这也会改掉它在 SSH 里的名字，所以默认是「否」）；之后也可以用 `install.sh name` 来改。
 - **重跑即更新。** 再次运行同一条命令即可原地更新已完成的安装：`~/.codeman/app` 中的本地改动会被 stash（绝不丢弃），运行中的服务会自动重启并校验。若首次安装中途失败，重跑会继续完成完整的安装流程。`install.sh status` 会再次打印 URL 和二维码；另外还有 `install.sh update`、`install.sh tailscale` 和 `install.sh uninstall`。
+- **无需管理员权限。** 在没有 `sudo` 的账户、安装器无法确认 `sudo` 权限的账户（不在 `sudo`、`wheel`、`admin` 组内，且 `sudo` 需要密码）或不是管理员的 Mac 账户上，安装器会把 nodejs.org 的 Node.js 和 tmux 项目自己的构建下载到 `~/.codeman/runtime`，两者都会校验 SHA-256；没有可用的 git 时，则以归档包的方式获取源码。`--no-admin` 强制走这条路线，`CODEMAN_NO_ADMIN=0` 则将其关闭。两个限制：Linux 上必须已有 make、C++ 编译器和 python3，tmux 下载需要 macOS 15 或更新版本。详见 [wiki](https://github.com/Ark0N/Codeman/wiki/Installation#without-administrator-rights)。
 - **给急性子的参数。** `curl -fsSL https://getcodeman.com/install | bash -s -- --tailscale --service` 直接在命令行上回答这些问题（还有 `--lan`、`--local`、`--run`、`--no-start`、`--name <n>`、`--port <n>`、`--yes`）。**CI / 无终端环境：** 没有终端时，涉及系统改动的步骤会带着说明中止，而不是静默执行；在自动化场景设置 `CODEMAN_NONINTERACTIVE=1` 即可批准这些步骤。

 On this route Node.js comes from nodejs.org (`latest-v<major>.x/SHASUMS256.txt` names the tarball AND carries its checksum, one fetch, no JSON parsing) into `~/.codeman/runtime/node`, and tmux from the tmux project's `tmux-builds` release into `~/.codeman/runtime/bin`. ⚠️ `tmux-builds` publishes no checksum file, so `tmux_build_sha256` pins all four digests of `TMUX_BUILD_VERSION`; bump the version and the digests together (the GitHub release API returns them as `digest`). ⚠️ A download is verified BEFORE it is unpacked or run, and an empty expected digest never passes. `node`, `npm`, `npx` and `tmux` are linked from `~/.local/bin` (`link_into_local_bin` refuses to replace a file that does not already point into the runtime, and uninstall removes only such links): the `codeman` launcher is `#!/usr/bin/env node`, and a non-interactive shell never reads the PATH line written to an interactive profile. The runtime's `node/bin` also goes on PATH and on the LaunchAgent's `svc_path`, since `npm install -g` puts AI CLIs beside that Node.js.
