feat: Add topological dependency scanning to task graph

This PR adds automatic topological dependency scanning to the task graph, allowing tasks to depend on tasks with the same name in dependent packages. Key changes include:

• Eagerly scan for topological dependencies between tasks based on package dependencies
• Add support for dependencies that are both explicit and topological with a new Both type
• Create a TaskIx newtype for better type safety in task graph indices
• Wrap TaskDependencyTypeInner in TaskDependencyType to provide safer API for checking dependency types
• Update task graph to use package indices instead of package paths for better performance
• Add tests for the new topological dependency scanning functionality
