Code Review
This pull request introduces a significant set of changes, primarily focused on updating dependencies like swc_core and refactoring the module graph handling within Turbopack. The changes simplify APIs by removing trait objects for module ID strategies and introducing more explicit and robust methods for creating module graphs and handling unused references. The dependency updates are extensive and bring the project up to date with next.js@16.2. Overall, these changes improve maintainability and modernize the codebase. My review found one potential compilation issue in the library chunking context.

This pull request includes a series of dependency updates, refactorings, and API changes across the codebase, primarily focused on improving module graph handling, updating dependencies, and simplifying interfaces for module IDs and unused references. The changes modernize how module graphs and binding usage information are managed, streamline configuration and context structures, and update several dependencies to newer versions.
Dependency updates:
Cargo.toml, includingswc_core,modularize_imports,react_remove_properties,remove_console,styled_components,styled_jsx,swc_emotion, andswc_relay. Also updated git sources forinclude_dirandmdxjs. [1] [2]Module graph and binding usage refactoring:
Refactored the module graph construction and binding usage info retrieval in
project.rsto use new APIs (from_single_graph,from_graphs,binding_usage_info, etc.), and changed how unused references are computed and returned, now using theUnusedReferencestype. [1] [2] [3] [4] [5] [6] [7]Updated the
module_idsmethod to return a concreteModuleIdStrategyinstead of a boxed trait object, and adjusted related context and config structures accordingly. [1] [2] [3]Codebase simplification and interface changes:
spawn_once_taskmethod fromBundlerTurboTasks, likely due to redundancy or changes in task handling.chunk_id_strategy::ModuleIdStrategyandUnusedReferences. [1] [2] [3]Configuration and context improvements:
content_type,query,module_type) to various config and condition structures to support more flexible configuration. [1] [2] [3]new_with_denied_paths_and_watched_ignoredfor more precise path control.Issue handling and diagnostics:
IssueFilterand using it inget_plain_issuesfor more flexible filtering. [1] [2]These changes collectively improve maintainability, flexibility, and performance, particularly in how module graphs and unused references are managed throughout the build process.
