Ship default config/panels/themes with the app: --init, XDG discovery, build/CI bundling

- tui-wm --init [DIR] writes an embedded default config.toml,
  panels/topbar.toml and themes/{dark,light}.toml (default target
  ~/.config/tui-wm, existing files untouched)
- Config discovery: ./config.toml wins, otherwise ~/.config/tui-wm/
  is used (process switches working dir there so panels/themes/saves/
  hot-reload all resolve consistently); spawned PTYs still start in
  the user's original working directory
- VS Code build tasks copy themes/ into builds/, dist/ sample configs
  refreshed with all new keys and the settings gear
- CI release now also uploads tui-wm-config.tar.gz (config + panels +
  themes) alongside the binaries
