docs(install): describe installer v2 and the Tailscale naming options
README, the Installation / Remote-Access / Running-As-A-Service wiki pages, docs/security-architecture.md and CLAUDE.md describe the three-question flow, the flags, the subcommands, the sub-path answer for an occupied :443 and why the rename is opt-in. docs/installer-v2-plan.md is the design and the verification record (what was measured, what still needs a fresh machine); docs/tailscale-installer-plan.md points at it.

### The name in the URL
|

|

The URL is the machine's MagicDNS name, so on a machine called `tnode` it is

`https://tnode.<tailnet>.ts.net`. Three ways to influence that, from least to most work:

| The machine's existing name (default) | Nothing. This is what the installer does unless you say otherwise. |
|
||||
| `https://codeman-<hostname>.<tailnet>.ts.net` | Answer yes to the installer's name question, pass `--name codeman-<hostname>`, or run `install.sh name`. This renames the machine tailnet-wide (SSH included), which is why the installer defaults to no. `install.sh uninstall` offers to rename it back. |
|
||||
| `https://codeman.<tailnet>.ts.net` | A [Tailscale Service](https://tailscale.com/docs/features/tailscale-services). Only a **tagged** node can host one (a device signed in with a user account cannot), the service is defined and approved in the admin console, and the feature is in beta. The installer does not set this up; it is a `tailscale serve --service=svc:codeman --https=443 127.0.0.1:3000` on a tagged host once the service exists. |
|
||||
|
||||
If `:443` on your node already belongs to another app, the installer offers Codeman under
|
||||
`https://<machine>.<tailnet>.ts.net/codeman` (the default, via `tailscale serve --set-path`
|

plus Codeman's `--base-url`), on a second port (`https://<machine>.<tailnet>.ts.net:8443`),
