Research direction
The issue is in the templates used by `bun init`. The package.json template uses tabs while tsconfig.json uses spaces. To fix, locate the template files in the Bun source code (likely under `packages/bun init` or similar directory) and ensure consistent indentation (preferably spaces) across all generated files. Review the existing templates for other JSON files to maintain consistency.
