package:pubviz v5.0.0

Breaking Changes

• Replaced positional commands (open, create, print) and the --format
  option with a unified --action (-a) flag.
• Default execution (pubviz) now functions identically to pubviz -a open.
• Removed the viz/dot.dart library. toDot is now exposed via a an extension
  on VizRoot

New Features

• Workspaces: Added the --workspace (-w) flag to visualize all linked
  packages within a Dart workspace.
• Output Controls: Added the --out-dir option to specify a target
  destination for generated HTML and offline capabilities.
• Serve Mode & Offline Support: Added the serve action which hosts the
  web app locally via dhttpd without booting up a new browser window. The
  open action now uses this local server to bypass strict file:// CORS
  restrictions internally. Additionally, the package now supports complete
  offline functionality by bundling compiled Dart web application assets (JS
  and WASM) directly inside the package.

Web UI Overhaul

• Completely redesigned the interactive web interface, adding a collapsible
  sidebar for cleaner zooming and display control.
• Added a z keyboard shortcut to easily toggle graph zoom capabilities.
• Improved graph styling: Primary packages now utilize a distinct background
  color to distinguish them easily.

Other Improvements & Fixes

• Modernized workspace discovery inside the codebase by utilizing structured
  JSON data directly from pub tool invocations.
• Hide version labels for primary node packages intentionally marked
  publish_to: none.
• Display a helpful warning message if pubviz runs inside a workspace root
  missing the --workspace flag.
• Fixed a bug causing wrong colors on hover interactions over outdated packages.
• Require sdk: ^3.10.0.
