Code Review
This pull request introduces tracking of transitive shader dependencies in DevelopmentShaderCompiler to determine if shaders need recompilation during DevFS syncs. It parses depfiles generated by impellerc and exposes areDependenciesModified to check for modified dependencies. Feedback highlights a potential FileSystemException when calling dep.statSync() in areDependenciesModified, which could crash the sync process and should be wrapped in a try-catch block.

Wrap dependency existence and stat checks in a try-catch block in areDependenciesModified to prevent crashing the DevFS sync process if a FileSystemException occurs.
