plushie/dev_server

Dev server: file watcher and recompiler for live reload.

Watches source directories for .gleam file changes, runs gleam build, detects changed BEAM modules, reloads them, and tells the runtime to re-render. The UI updates without losing application state.

Started automatically when dev: True is set in StartOpts. Requires the file_system Erlang package.
