feat: update X-Client-Info to use structured semicolon-delimited metadata#1362
Conversation
…data Consolidates platform and runtime metadata into the existing X-Client-Info header using semicolon-delimited key=value pairs instead of separate headers. New format: supabase-dart/2.x.x; platform=linux; platform-version=...; runtime=dart; runtime-version=3.7.2 supabase-flutter/2.x.x; platform=linux; platform-version=...; runtime=dart; runtime-version=3.7.2 Removes X-Supabase-Client-Platform and X-Supabase-Client-Platform-Version headers since adding new standalone headers is a breaking change for supabase-js in Edge Functions (users must explicitly allow headers in CORS).

Summary
Consolidates platform and runtime metadata into the existing
X-Client-Infoheader using semicolon-delimitedkey=valuepairs, removing the separateX-Supabase-Client-PlatformandX-Supabase-Client-Platform-Versionheaders.New format
Changes

Adding new standalone headers (like
X-Supabase-Client-Platform) is a breaking change forsupabase-jsin Edge Functions — users must explicitly allow headers in CORS config. SinceX-Client-Infois already allowed everywhere, embedding metadata there can be extended freely without touching CORS.Testing
