Pull request overview
Adds a reusable Copilot prompt document to guide systematic “public interface/contract” reviews for PRs that change exported APIs, schemas, or wire formats.
Changes:
- Introduces a new prompt file with a step-by-step workflow to identify and classify public-surface changes by compatibility risk tier.
- Defines a per-interface reporting template, common compatibility failure modes to check, and a test-change audit checklist.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

.github/prompts/pr-interface-review.md— a Copilot prompt file for systematic per-interface review of PRs that touch the public surface (types, schemas, exported symbols, wire formats, CLI flags).The prompt classifies every signature change into one of six tiers (🚨 breaking through 🆕 brand-new), flags compat measures already taken, and calls out gaps that remain. Specifically catches subtle failure modes — class→alias collapse, read-side vs write-side compat, default-value flips, enum widening, async/sync flips, generic variance changes.
