Refactor package compiler to accept dependencyPaths and build a global symbol table from dependencies' exports.json (prefers explicit URIs, falls back to inferred package: URIs). Split file processing into _parseFile and _generateJS phases, populate local exports into the global table, and run JS generation with an updated importRewriter that preserves package: URIs (converts .dart -> .js). Add verbose/debug logging and diagnostics for symbol resolution and package scanning. Fix declaration extraction: propagate extension-type metadata, log debug info, and record generic typedefs. Also include many generated JS artifacts, source maps and package metadata updates (exports.json / package.json) across flutterjs_dart, foundation, services, widgets, engine, gen, runtime, tools and other packages.

… target

- run_command.dart: add _ensureNodeModulesForNodeTarget() — creates
  node_modules/flutterjs_X junctions before launching node server so
  `import 'flutterjs_server'` resolves without requiring `flutterjs get`
- code_pipleiline.dart: skip web-only @flutterjs packages (material,
  widgets, vdom, seo, etc.) from PackageRegistry when target is node,
  preventing symbol table pollution with browser-only widget names
- runtime_package_manager.dart: when linking @flutterjs/X SDK packages
  also link under the Dart name (flutterjs_X) in root node_modules

…ge improvements

Core compiler:
- Add ImportExportTracker and ImportExportModel for accurate cross-file import analysis
- Add EnumDecl IR node and EnumCodeGenerator for proper enum → JS object translation
- Fix CascadeExpressionIR scanning in ImportAnalyzer and FileCodeGen
- Fix null comparison semantics (== null uses loose equality to catch undefined)
- Fix Map cast to use typeof check instead of instanceof Map
- Remove hardcoded identifier hacks in ExpressionCodeGenerator

Node.js server target:
- Add flutterjs_server package (Dart API + JS runtime with HTTP server, router, middleware)
- Add dart_api example: full REST API demo compiled from Dart to Node.js
- PackageRegistry: filter web-only @flutterjs packages for node target builds
- RuntimePackageManager: also link @flutterjs/X as flutterjs_X in root node_modules
- RunCommand: auto-link node_modules before starting node server (_ensureNodeModulesForNodeTarget)

Import generation:
- GlobalSymbolTable wired to ModelToJSPipeline after package manifests load
- PackageRegistry.buildGlobalSymbolTable() maps symbols to full package: URIs
- Fix hardcoded material imports registered in symbolToPath to prevent duplicates

Package updates:
- flutterjs_foundation, flutterjs_gestures, flutterjs_material, flutterjs_services,
  flutterjs_widgets: updated exports.json, build.js, src/index.js
- flutterjs_dart: add ui_web dist, pubspec.yaml
- flutter_web_plugins: add JS package
- Add tool/ scripts for build, check, fix-imports, reset
