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

+Description: persistent browser terminal for Claude Code
+ DevDesk serves a LotusGuild-styled web terminal (ttyd with an xterm.js
+ front end) whose sessions live in a dedicated tmux server. Closing the
+ browser, restarting the web service or upgrading the package never stops
+ the Claude Code processes; after a reboot each named session resumes its
+ own conversation.
+ .
+ Authentication and TLS are expected to be handled by a reverse proxy
+ (Nginx Proxy Manager + Authelia), which also injects the ttyd credential.
