fix(aider): use replace to swap out the messages view

[Kubuxu]

We need to swap them becasue the wildcard seems to be avaluated at the
view creation time.

[Copilot]

Pull Request Overview

This PR updates the view creation logic to ensure wildcard-based parquet file selections are re-applied each time by using OR REPLACE instead of IF NOT EXISTS.

• Switches CREATE VIEW IF NOT EXISTS to CREATE OR REPLACE VIEW in createOrReplaceMessagesView.
• Retains the existing parquet union logic.

• [nitpick] Consider adding a comment above this line explaining why OR REPLACE is required to ensure that updates to the wildcard file pattern are applied correctly when the view is recreated.

	createView := fmt.Sprintf(`CREATE OR REPLACE VIEW messages AS SELECT * FROM latest_messages %s`, includeParquetFiles)

observer/observer.go:215

• Add unit tests for createOrReplaceMessagesView covering both includeParquet=true and includeParquet=false to verify the correct SQL is generated and executed under each scenario.

	if includeParquet {
