v0.2.3

Admit quasar 0.2 alongside 0.1

Its subscribe answers void there instead of a promise that resolved even
on failure. Nothing here awaited that return value, so both majors work.

Keep the dev-dependency alignment, drop the workspace: protocol

The internal ranges had been rewritten to workspace:^. That resolves inside
this monorepo and nowhere else: every package CI checks out its own repository
alone and runs pnpm install, where the protocol has no workspace to point at
and fails with ERR_PNPM_WORKSPACE_PKG_NOT_FOUND before a single test runs. The
concrete ranges are back; the dev-dependency bumps that came with the same edit
are kept, and now match what the lockfile already resolved.
