fix(ui): improve progress bar message readability

[jhamon]

Problem

When loading datasets, the progress bar displays grammatically awkward messages like:

• "Loading documents parquet files"
• "Loading queries parquet files"

The issue is using plural nouns ("documents", "queries") as adjective modifiers before "parquet files", which reads unnaturally.

Solution

Simplified the progress bar description to just "Loading documents" and "Loading queries". Since all dataset files are stored exclusively as parquet format (this is enforced in the code), mentioning "parquet files" is redundant implementation detail that doesn't help users.

Changes

• Updated dataset_fsreader.py line 99: changed tqdm description from f"Loading {data_type} parquet files" to f"Loading {data_type}"
• Results in cleaner, more professional progress messages

Testing

• ✅ All 190 tests pass (3 skipped as expected)
• ✅ No breaking changes
• ✅ Backward compatible - only affects UI text

Example

Before:

Loading documents parquet files: 100%|████████| 2/2 [00:01<00:00,  1.23it/s]

After:

Loading documents: 100%|████████| 2/2 [00:01<00:00,  1.23it/s]

The simpler message is easier to read and sounds more natural while conveying the same information to users.

Note

Low Risk
Low risk: only changes the tqdm progress bar description string during dataset parquet loading, with no impact on IO, parsing, or schema validation logic.

Overview
Improves dataset loading UX by simplifying the tqdm progress message in DatasetFSReader._safe_read_from_path from “Loading {data_type} parquet files” to just “Loading {data_type}”, removing redundant/awkward wording while keeping behavior unchanged.
