## Summary by CodeRabbit
- **New Features**
- Added enhanced error handling and user-friendly error messages in
quick search and document search menus.

- Quick Search now provides explicit error feedback in the UI.
- **Improvements**
- Search and aggregation operations can now prefer remote or local
indexers based on user or system preference.
- Streamlined indexer logic for more consistent and reliable search
experiences.
- Refined error handling in messaging and synchronization layers for
improved stability.
- Enhanced error object handling in messaging for clearer error
propagation.
- Updated cloud workspace storage to always use IndexedDB locally and
CloudIndexer remotely.
- Shifted indexer operations to use synchronized indexer layer for
better consistency.
- Simplified indexer client by consolidating storage and sync layers.
- Improved error propagation in messaging handlers by wrapping error
objects.
- Updated document search to prioritize remote indexer results by

Change the query for querying quota of Cloud Blob Storage.
The original query used new fields, which caused errors in the old version of the server. This PR uses a simpler query to ensure compatibility.
<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit
- **New Features**
- Added the ability to retrieve a workspace's blob storage quota, including both the raw limit and a human-readable format, via a new query.
- **Bug Fixes**
- Updated quota retrieval to use the new blob-specific quota query for improved accuracy.

## Add Markdown Preprocessor Extension and Enhanced LaTeX Support
### Markdown Preprocessor Extension
This PR introduces a new preprocessor extension for Markdown adapters that allows preprocessing of content before conversion:
Adds a new PreprocessorManager for handling text transformations
Introduces extensible preprocessor interface that supports different processing levels (block/slice/doc)
Integrates preprocessor extension into the existing Markdown adapter workflow
### LaTeX Support Enhancement
Extends LaTeX support to handle both traditional and alternative syntax:
Adds support for backslash LaTeX syntax:
Block math: ```\[...\] ``` alongside existing ```$$...$$```
Inline math: ```\(...\) ``` alongside existing ```$...$```
Implements LaTeX preprocessor to standardize syntax before conversion
Updates tests to cover both syntax variants
