Some query/export formats fall back to default output instead of specified format

[teaguesterling]

Description

Several format options for the query and export tools don't produce the expected output format, instead falling back to a default tab-separated format with type headers.

Affected Formats

Query Tool

• jsonl - Returns tab-separated instead of JSON Lines
• table - Returns tab-separated instead of ASCII table
• box - Returns tab-separated instead of box-drawing table

Export Tool

• jsonl - Same issue as query tool
• table / box - Same issue as query tool

Working Formats

• json ✅
• markdown ✅
• csv ✅

Example

SELECT * FROM users

With format: "jsonl", expected:

{"id":"1","name":"Alice","email":"alice@example.com"}
{"id":"2","name":"Bob","email":"bob@example.com"}

Actual:

id	name	email	created_at	
INTEGER	VARCHAR	VARCHAR	DATE	
[ Rows: 4]
1	Alice	alice@example.com	2024-01-15
2	Bob	bob@example.com	2024-02-20

Notes

• parquet format for export also falls back to tab-separated, but parquet is a binary format so it doesn't make sense as a text return value anyway. Consider removing it as an option or only supporting it when an output file path is specified.
