🎯 What: Adds missing test coverage for the exact resize load factor boundary in echo-core-zig/src/data/hashmap.zig.
📊 Coverage: Specifically tests the exact edge-case element insertion that trips the count >= entries.len * 3 / 4 limit, guaranteeing the map correctly doubles in size, counts correctly, and persists older keys without data loss or regressions.
Result: Improved test coverage verifying the stability of internal hashing behavior across resize threshold boundaries.

Adds a specific test for the `HashMap` resize logic checking the exact behavior at the load factor limit (count >= entries.len * 3 / 4) and ensuring data persistence.
