Introduce a new `--remove-acroform` option to remove the interactive form dictionary from the document catalog. Update related documentation, tests, and release notes to reflect this new feature.

Fixes #1403

Avoid confusing latest CLion version.

…r improved clarity and safety. Update related methods and references accordingly.

- Move AcroForm-related methods (`analyze`, `traverseField`, `getOrCreateAcroForm`, etc.) from `QPDFAcroFormDocumentHelper` to the `AcroForm` class.
- Update method calls across files to reflect changes.
- Improve comments for methods to align with PDF specifications.

Add a new configurable limit `--max-stream-filters` to address excessive stream filters in damaged or specially constructed PDFs. Update related documentation, tests, and release notes to reflect this feature.

Introduce `qpdf::global::inspection_mode` for analyzing and repairing damaged PDFs with a restricted feature set. Update relevant code to enforce restrictions and add supporting test cases.

…ted tests, documentation, and references across the codebase.

Enhance the `global` namespace by introducing `limit_errors` for tracking the number of exceeded limits. Update related tests and documentation to ensure functionality and clarity.

- Modify `traverseField` to return `bool` for identifying invalid fields.
- Add `bad_fields` set to track and handle problematic fields.
- Improve error handling for invalid parent entries.

- Add null pointer checks for schema objects.
- Refactor `checkSchemaInternal` for better readability and maintainability.
- Replace redundant error construction logic with lambda-based approach.
- Simplify array and dictionary schema handling.
- Remove unused test coverage statistics.
