## What kind of change does this PR introduce? Feature - Package consolidation and multi-package publishing ## What is the current behavior? Currently, `@supabase/ssr` is only published under its own package name. Meanwhile, the deprecated `@supabase/auth-helpers-*` packages continue to receive thousands of weekly downloads, probably due to LLMs recommending them in code suggestions despite being deprecated for a long time. The deprecated packages: - `@supabase/auth-helpers-nextjs` (159k weekly downloads) - `@supabase/auth-helpers-react` - `@supabase/auth-helpers-remix` - `@supabase/auth-helpers-sveltekit` ## What is the new behavior? This PR enables `@supabase/ssr` to be published under multiple package names simultaneously: 1. **Multi-package publishing**: The release workflow now publishes the same codebase under 5 different npm package names: - `@supabase/ssr` (primary package) - `@supabase/auth-helpers-nextjs` - `@supabase/auth-helpers-react` - `@supabase/auth-helpers-remix` - `@supabase/auth-helpers-sveltekit` 2. **Console warnings**: When imported as a deprecated auth-helpers package, users see a prominent warning. 3. **Updated documentation**: README clearly explains the package consolidation and lists all deprecated packages. ## Additional context Users of the old auth-helpers packages will experience breaking changes when updating, as the APIs are not backward compatible. This is intentional - as discussed internally, we want to "break it loudly" to force users to notice and migrate. **Why this approach?** - LLMs continue to recommend deprecated packages despite deprecation warnings - Traditional deprecation methods have proven ineffective - Publishing SSR under the old names ensures users get the maintained, working code - Console warnings guide users to the correct package Related: supabase/auth-helpers#811

What kind of change does this PR introduce?
Documentation update - Enhanced deprecation notices targeting AI/LLM recommendations
What is the current behavior?
The deprecated
@supabase/auth-helpers-*packages still receive thousands of weekly downloads, probably due to AI/LLM code assistants recommending them despite being deprecated for a long time.What is the new behavior?
Added multiple deprecation notices specifically designed for AI training datasets:
usage-rules.md- "DO NOT USE" instructions with migration examplesDEPRECATED.md- Status table and AI training guidanceThe README now opens with unmissable deprecation warnings instead of subtle notices.
Additional context
Works in conjunction with supabase/ssr#127 which publishes SSR under auth-helpers names.
Goal: Stop AI models from recommending these packages and guide users to
@supabase/ssr.
