data-table: double-click a cell to add a filter by value

[yan-hic]

📝 Summary

Add a small UX enhancement to the data table: double‑clicking a cell adds a “filter by value” for that column. This reuses the existing filter mechanism and integrates with the filter pill UI.

🔍 Description of Changes

Add a minimal double‑click handler that:

• No‑ops if the column cannot be filtered or lacks a filter type
• Otherwise applies a select filter with the cell’s value using the existing Filter.select utility

Wire the handler to each table cell’s onDoubleClick

Behavior: Double‑clicking a cell creates a pill like “ is in []” and filters rows accordingly

hey @yan-hic - thank you for the contribution, we are going to discuss with the team to see if this is something we'd like to add/support

Hey Miles, how can I/you hold up on this? I like to propose another change instead namely a cell context menu to filter in or out (like Airtable). That would mean also adding the "is not in" filter operator.
Could add more operators like regex but it's probably best handled upstream, in another cell.

adding a context menu could make sense as well. i think that is more intuitive than a double click anyways.

if we did add a context menu, we would need to support other commands like Copy and Copy Selected in case there are multiple cells selected.

Filter to include or exclude also makes a lot of sense.
