90690dfab4 Remove TestCoreWhitespace test
The whitespace control functionality has been intentionally disabled as indicated by comments in whitespace.go. This test was previously skipped, and has now been removed to avoid confusion.

This functionality may be reimplemented in the future, at which point the test can be added back.

a38fa8631a Fix array filters and add support for GetItemNode and array access
This commit fixes the TestArrayFilters tests by implementing proper support for array access and map literals in the template engine. Key improvements include:

1. Added support for GetItemNode to handle array access with square brackets
2. Implemented parseMapExpression to handle map/object literals with curly braces
3. Fixed string ordering in the Keys filter by adding proper sorting
4. Added support for array access in variable attributes
5. Improved the expression parsing to handle chained operators properly

These changes allow complex expressions like {{ people[0].name }} to work correctly
and ensure that array filters like sort, keys, and merge function properly.

- Added documentation about the parser limitations with negative numbers
- Updated FINDINGS.md and PROGRESS.md to track the improvements
