Summary of Changes

Hello @fireairforce, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a reported issue (referenced as #2388) by adding a comprehensive snapshot test case. The test is designed to specifically validate the behavior of the define configuration option when a defined value, such as an enum, becomes exceptionally large. By simulating this edge case, the PR aims to ensure the pack system correctly handles substantial define values, preventing potential failures or incorrect evaluations.

Highlights

• New Snapshot Test Case: Introduced a new snapshot test under "crates/pack-tests/tests/snapshot/define/complex" to reproduce a bug where a very large define value in the configuration prevents the define mechanism from functioning as expected.

Code Review

This pull request introduces a new snapshot test case to address an issue where define values, particularly large ones, were not working as expected. However, the generated output for the test case indicates that the define replacement is not being applied to the RoutePathEnum identifier. This suggests that the underlying issue might not be fully resolved, or the define transformation step is not correctly integrated into the bundling process for this module. The test, in its current state, does not verify the intended fix.
