* feat: migrate distributed nodes to native ComfyUI V3 API
* fix: hide Distributed Value backing fields in Nodes 2.0
Use native widget visibility without converting backing fields into sockets. Preserve widget types, serializers and options identity; cover edits, reload, worker refresh and linked widgets.
* fix: isolate local worker databases and avoid port conflicts
* fix: harden local worker startup preflight and database paths
Handle auto-launch before the master binds, allow TIME_WAIT restarts without accepting active listeners, resolve relative paths in the worker cwd, and round-trip SQLite URLs through SQLAlchemy. Add regressions and remove the README additions.
