Fixes #4601: Exclude Terraform and Terragrunt cache directories from checkpoints

[cte]

Summary

Closes #4601

This PR fixes issue #4601 by adding and directories to the checkpoint exclusion patterns, preventing these large cache directories from being included in snapshots and reducing disk space usage.

Changes Made

• Added and to the function in
• Updated tests in to verify the new exclusion patterns are included

Problem Solved

When working on Terraform/Terragrunt IaC projects, Roo Code's checkpoint system was including large cache directories in snapshots, consuming excessive disk space. Early in a project, these paths may not be included in .gitignore, so they were saved in every checkpoint, sometimes consuming 10x more disk space than needed.

Solution

The checkpoint system will now automatically exclude these directories from all checkpoints, just like other build artifacts (node_modules/, .gradle/, etc.). The checkpoint system writes these patterns to .git/info/exclude in the shadow repository, ensuring Git ignores them regardless of .gitignore.

Testing

• All existing tests pass
• Added test coverage for the new exclusion patterns
• Verified that and are now included in the exclude patterns

Acceptance Criteria Met

✅ Given I'm working on an initialized Terraform|Terragrunt project with downloaded providers and without .terraform|.terragrunt-cache in .gitignore
✅ When I run work on a task and Roo Code creates checkpoints
✅ Then the .terraform|.terragrunt-cache directory is automatically excluded from checkpoints
✅ And checkpoint size remains small, comparable to projects without Terraform caches
✅ But my actual Terraform/Terragrunt configuration files (.tf, .hcl, etc.) are still included

Fixes #4601

Important

Adds .terraform/ and .terragrunt-cache/ to checkpoint exclusion patterns in excludes.ts to reduce disk space usage.

• Behavior:
  • Adds .terraform/ and .terragrunt-cache/ to exclusion patterns in getBuildArtifactPatterns() in excludes.ts.
  • Updates getExcludePatterns() in excludes.ts to include new patterns.
• Testing:
  • Updates tests in excludes.spec.ts to verify .terraform/ and .terragrunt-cache/ are excluded.
  • Ensures tests cover scenarios with and without .gitattributes file.

This seems fine but I'm not sure if we want to make this list grow more, it might be better to just prevent the addition of directories with a very large amount of files to the checkpoints
