fix(plugin-record-hook): rethrow errors instead of swallowing them

[devin-ai-integration]

Please explain how to summarize this PR for the Changelog:

fix(plugin-record-hook): Errors during record hook execution are now properly propagated instead of being silently swallowed. Previously, errors were logged but the function would return normally, causing executions to appear successful even when record updates failed.

Tell code reviewer how and what to test:

Context: This fix addresses an issue where bulk record hook updates could fail silently. When event.update() failed, the error was caught, logged, and then the function returned without indicating failure. This caused agent executions to be marked as successful even when validation results weren't persisted.

Changes:

1. Outer catch block: Changed from return to throw e so errors propagate to the listener runtime
2. Inner catch block: Preserved the original error message instead of throwing a generic "Error updating records" message

Review checklist:

• Verify this behavioral change is acceptable (errors now cause execution failures instead of silent success)
• Consider if this warrants a major version bump as a breaking change
• Note: The root cause of silent failures is in @flatfile/listener's AuthenticatedClient.fetch() which swallows errors. This fix helps surface errors that DO get thrown, but won't catch cases where fetch() silently returns undefined

To test:

1. Create a record hook that processes records
2. Simulate a failure in event.update() (e.g., network error, invalid data)
3. Verify the error now propagates and marks the execution as failed
