Option to Enable Index Usage by Default for All Models

[LVincent555]

Description:
Hi, I'd like to suggest an improvement regarding the default behavior of model interactions with indexed codebases.

Currently, regardless of which model is being used, the system does not automatically utilize the existing index by default — even when the codebase has already been indexed. This means that during a task, the model often starts reading files directly from disk, which can be slow and inefficient. Users have to manually pause the task and explicitly instruct the model to "use index" in order to leverage the pre-built index.

It would be great if there was an option in the settings to enable index usage by default. This way, when a codebase is already indexed, the model would automatically prefer the indexed data unless specified otherwise.

This small change could significantly improve workflow efficiency, especially for larger projects where indexing is already in place. It would eliminate the need to repeatedly interrupt tasks just to enable index usage manually.

Thanks for considering this suggestion!

Additional Information:
Current Behavior: Models do not use the index by default, even when it exists.
Proposed Solution: Add a setting to enable index usage by default.
Impact: Improved performance and smoother workflow for users working with indexed codebases.
Why This Matters:
Reduces manual intervention required to switch to index usage.
Enhances efficiency, especially for large codebases.
Aligns with user expectations when an index is available.
