Move the CLI application from packages/server/ to apps/cli/ to align
with the monorepo convention (apps/ for deployable applications,
packages/ for shared libraries). Rename package to @openchatlab/chatlab.
Also fix a bug in ensureToken() that used raw string manipulation to
write config.toml, causing duplicate token fields that corrupted the
TOML file. This led to config parse failures and user_data_dir being
overwritten with defaults. Now uses writeConfigField() for safe writes.
Adds a zero-dependency Node.js script with arrow-key selection
for choosing between Desktop (Electron), Web (CLI serve + frontend),
Server Only (API backend), and Frontend-only dev modes.
Remembers last selection in node_modules/.cache/dev-mode.
tsx watch's symlink-based file watching doesn't trigger on changes to
pnpm workspace packages (tsx#221). Add --include flags for packages/core
and packages/node-runtime source directories to both dev:serve script
and vite.web.config.mts auto-serve plugin. Extract long command to
scripts/dev-serve.sh for cleaner package.json.
