The db-dtypes package is required for BigQuery to properly handle database-specific data types when returning query results. Without it, users encounter errors when querying BigQuery databases. This package was already included in the postgres extras but was missing from bigquery.

Pull request overview
This PR softens how tool errors are presented so that transient or recoverable failures look like part of an intelligent retry process rather than alarming breakages.
Changes:
- Backend: updated
RunSqlTooland agent task detail messaging to use “Trying alternative approach” language and lower-severity notification levels for SQL errors. - Frontend components: replaced ❌ error/failed icons with ✅ and adjusted progress/task list visuals so error states share the same friendly iconography.
- Shared styles: updated several error-related styles in
rich-component-styles.tsto use green/“positive” tokens instead of red/“negative” ones for error/failure badges, notifications, and tool error sections.

The detail string "Tool {'completed successfully' if result.success else 'trying alternative approach'}" will render as "Tool trying alternative approach" in the error case, which is slightly ungrammatical and less clear than something like "Tool is trying an alternative approach"; consider adjusting the wording while keeping the success-path text unchanged.

The PR description says rich-component-styles.ts "Changed all error-related CSS from red to green", but within this file there are still error styles using negative/red tokens (e.g., .progress-fill.status-error, .log-entry.log-error, .chart-error, .progress-display-fill.status-error), so the description is misleading unless those are intentionally left red; consider either updating those remaining selectors or narrowing the PR description to the specific components you restyled.
Summary
Why
When tools encounter errors and retry, the current UI shows alarming red error messages that make users think something is broken. In reality, the agent is intelligently trying alternative approaches. This PR makes those states appear friendly and reassuring.
