Matrix SDK Workspace

This workspace is the isolated SDK incubation area for WORKSTREAMS/matrix-sdk-isolation.

Current proven checkpoints:

• copied SDK-bearing packages build/test/type-check/pack independently
• copied package identities were renamed to final @open-matrix/* names
• @open-matrix/sdk facade package builds/tests/packs
• @open-matrix/browser-kit builds package-manager-ready dist exports
• a fresh external temp consumer installs packed tarballs, compiles, starts a MatrixActor, and calls it through the Matrix runtime/transport path

Proof commands:

pnpm --dir projects/matrix-sdk prove
pnpm --dir projects/matrix-sdk prove:external-consumer

Matrix-3 consumers have not been repointed yet.
