feat(cli): codeman web -d and codeman service install (#231)

Browse Source 
Two ways to keep the server running, split by how long it should last.

`codeman web -d` relaunches the same entry script detached (setsid), with
`--stop` and `--status` alongside it. A pidfile and log live in the data
dir. `nohup` is not what makes this work: Node re-arms SIGHUP to its
default disposition even when it inherits "ignore", and cli.ts handles
SIGHUP with a graceful shutdown, so a delivered HUP still stops the
server. Removing the shell's ability to send one is the fix.

`codeman service install|uninstall|status` writes and loads the systemd
user unit or the LaunchAgent, with the installing shell's PATH baked in
(launchd hands a job /usr/bin:/bin:/usr/sbin:/sbin, which finds neither a
Homebrew/nvm node nor tmux/claude). install.sh already covers one-liner
installs; this is for npm globals.

Both refuse to start when a server is already up on the data dir, since a
second instance on the shared tmux socket attaches PTYs to the first
one's live sessions. Both poll /api/status until the child answers or
dies rather than reporting a success they have not seen. `--stop` checks
the pid still looks like a Codeman server before signalling it.

The systemd unit name and launchd label move to config/service-names.ts
so install.sh, detectSupervisor() and service install cannot drift into
supervising two copies. Instance-scoped, unchanged for the default
instance.
