feat: DevDesk v0.1.0, a persistent browser terminal for Claude Code

ttyd serves a single-file xterm.js UI styled with the LotusGuild TDS
(web_template base.css). Sessions live in a dedicated tmux server unit
(devdesk-tmux.service), so restarting or upgrading the web unit never
stops Claude. Each named session maps to a project directory. A Claude
SessionStart hook records the conversation ID, so after a reboot the
session resumes that exact conversation.

- bin/devdesk: attach / new / ls / end / pick, with an fzf picker
- ttyd requires a credential that NPM injects; origin check enabled
- debian/: dh 13 with --no-stop-on-upgrade for the tmux unit, bundled
  sha256-verified ttyd 1.7.7, lintian overrides, man page
- CI: lint, test, build, smoke-test, artifact; v* tags publish to the
  Gitea apt registry and create a release

Deploying DevDesk (CT 126 · dev.lotusguild.org)

1. Install the package

Add the Gitea apt repository once:

curl -fsSL https://code.lotusguild.org/api/packages/LotusGuild/debian/repository.key \
  -o /etc/apt/keyrings/gitea-LotusGuild.asc
echo "deb [signed-by=/etc/apt/keyrings/gitea-LotusGuild.asc] https://code.lotusguild.org/api/packages/LotusGuild/debian bookworm main" \
  > /etc/apt/sources.list.d/lotusguild.list
apt update && apt install devdesk

On install, /etc/devdesk/secret.env is generated, devdesk-tmux.service and devdesk.service are enabled and started, and ttyd listens on :7681. Requests without the credential get a 401.

2. Nginx Proxy Manager (CT 139)

Proxy host: dev.lotusguild.org → http://10.10.10.58:7681.
- Websockets Support on.
- SSL: the existing wildcard *.lotusguild.org certificate, with Force SSL.

Advanced tab: paste npm-advanced.conf, replacing __DEVDESK_BASIC__ with the output of:

. /etc/devdesk/secret.env && printf '%s' "$DEVDESK_CREDENTIAL" | base64 -w0

Why the credential matters: ttyd only checks the credential, so anything on the LAN that bypasses NPM is refused. If you rotate it, delete secret.env, run dpkg-reconfigure devdesk, update NPM, then systemctl restart devdesk.

3. Authelia (CT 167)

Add these to access_control.rules in /etc/authelia/configuration.yml, above any broader *.lotusguild.org rule:

- domain: dev.lotusguild.org
  policy: two_factor
  subject: ['user:jared']
- domain: dev.lotusguild.org
  policy: deny

Then run authelia validate-config --config /etc/authelia/configuration.yml && systemctl restart authelia.

4. DNS

Cloudflare: add a CNAME dev → apex, DNS-only (grey cloud).
Pi-hole: add "10.10.10.27 dev.lotusguild.org" to dns.hosts in pve-infra/containers/163-pihole/etc/pihole/pihole.toml. A push auto-deploys it, and LAN clients then reach NPM directly instead of hairpinning.

5. Optional hardening

Enable the Proxmox firewall on CT 126 (firewall=1 on net0) and allow tcp/7681 only from 10.10.10.27. The same rule suits code-server on :8680.

Operations

Task	Command
Sessions	`devdesk ls`
Attach over SSH	`devdesk attach <name>` (or `devdesk pick`)
End a session	`devdesk end <name>` (or `[x]` in the Claude window's exit menu)
Restart the web side (safe)	`systemctl restart devdesk`
Stop every session	`systemctl stop devdesk-tmux`
Logs	`journalctl -u devdesk -u devdesk-tmux`
UI-only update	replace `/usr/share/devdesk/index.html` (ttyd re-reads it per request)
