**Issue #3607393: Fix getLoaderOptionsSchema() silently discarding new html_processor pipeline options**
Fixes silent option loss when new html_processor pipeline options are passed
through this module. Options added to html_processor after initial release
were silently ignored with no warning.
**Other**
- Sets LLM visibility defaults for all pipeline options
- Bumps minimum PHP to 8.2
- Fixes PHPUnit 11 deprecation in phpunit.xml.dist
Issue #3575582 by webbywe: Update module for Document Loader 2.x and html_processor 1.0-rc1 compatibility. Extracts all HTML processing services to the standalone html_processor module; this module becomes a bridge plugin. Adds the document_loader_html_processor_url opt-in submodule for URL fetching.
First Release Candidate (RC1) for the Document Loader: HTML Processor module. This version is considered feature-complete and is ready for broader testing. This release transitions the module from development status toward a stable 1.0.0 release.
