docs: Update query examples to use eq() helper for boolean comparisons

[KyleAMathews]

🎯 Changes

fix #1297

Updated documentation examples and code comments to use the eq() helper function for boolean field comparisons in .where() clauses instead of relying on implicit boolean coercion.

Changes made:

• Updated import statements to include eq from @tanstack/react-db and @tanstack/db where needed
• Replaced implicit boolean comparisons (e.g., !todo.completed, product.in_stock, u.active) with explicit eq() calls (e.g., eq(todo.completed, false), eq(product.in_stock, true), eq(u.active, true))
• Updated examples across:
  • docs/guides/schemas.md (todo and product examples)
  • docs/collections/trailbase-collection.md (todo example)
  • docs/reference/classes/BaseQueryBuilder.md (API documentation)
  • docs/overview.md (overview example)
  • packages/db/src/query/builder/index.ts (JSDoc comments)

This change promotes consistency and clarity in query syntax by using the explicit eq() helper for all boolean comparisons, making the intent clearer and aligning with best practices for query building.
