[Bug] Temporary file tmp-builder-codes-outline.mdx committed to master branch

## Description
The file `tmp-builder-codes-outline.mdx` (prefixed with `tmp-`) is committed
to the `master` branch and publicly visible. This appears to be a temporary
working file that should not be in production.

## Location
`/tmp-builder-codes-outline.mdx` (root of master branch)

## Impact
- Exposes incomplete/draft documentation to end users
- Misleads developers with potentially unreviewed content
- Clutters the repository root with non-production files

## Suggested Fix
- Remove the file from master branch
- If content is needed, move it to the proper docs/ section
