PR-Safe Code Formatter API (Prettier + Diff for CI/CD)

Deterministic, production-grade code formatting with PR-ready unified diffs — built for teams, CI pipelines, and automated pull requests.

🚀 What this API does

This is not a generic beautifier. It is designed for professional engineering workflows where formatting must be:

Instead of only returning “pretty code,” you get:

Prettier-formatted output
A real Git-style unified diff you can apply directly in GitHub/GitLab/Bitbucket
Change metrics for CI checks
A validate-only mode that fails fast without modifying your code

This makes the API ideal for:

Default: default

Default: full

Production formatting with diff

CI compliance check (no mutation)

Partial fixes (line-specific)
