Interactive prompts should always be written to stderr. Can you double check the implementation of PromptProjectRef?

Ah aight, Fixed to always use stderr.
Removed the conditional and now always passing tea.WithOutput(os.Stderr).
PromptProjectRef correctly passes opts through to PromptChoice.
Tested with supabase gen types > file.ts and output is clean.

Summary
Fixes interactive prompts being written to output files when using stdout redirection with
supabase gen types.Problem
When running
supabase gen types > types.ts, the interactive project reference prompt was being written to the output file instead of the terminal. This corrupted the generated TypeScript file with prompt text.Solution
Interactive prompts now always write to stderr by passing
tea.WithOutput(os.Stderr)to the Bubble Tea program inproject_ref.go. This ensures prompts remain visible in the terminal while keeping stdout clean for piped output.Related
