Summary

Support DeepSeek Harness 0.2.1-rc.2. With the previous adapter, an extension authenticates successfully (hello.ok) and immediately disconnects with stream-failed: Cannot read properties of undefined (reading 'signal') because the Gateway now requires an explicit Peer.

Changes

• Create an owner Peer through Connection, scoped to the bridge plugin, and reuse it for unary calls, event/session/workspace streams, and $events/result replies. Peer identity is constructed by the host rather than read from extension payloads.
• Align DSH runtime, bridge peers, Cordis dependencies, and the lockfile with 0.2.1-rc.2; replace dsh-subagent-in-process-driver with dsh-subagent-spawn-in-process.
• Remove the empty invariant companion and its setup hook because dsh-invariants is no longer published for this release. Adapt JSONL persistence fixtures to its named plugin exports.
• Update English/Chinese installation instructions and both installer launch commands.

Testing

On macOS arm64 with Node.js 25.8.2 and pnpm 11.7.0:

• Bridge tests: 151 passed; extension tests: 394 passed.
• pnpm run typecheck, pnpm run check:runtime, and pnpm peers check passed.
• pnpm run build, bash -n scripts/install.sh, and git diff --check passed.
• pnpm run test:smoke passed against the real 0.2.1-rc.2 host in an isolated DSH home: discovery, token authentication, create/list/history, persisted model selection, V2 migration, browser snapshots, and prepared projections after restart. This smoke test reproduced the disconnect before the Peer fix.
• Added regression assertions that unary calls, one-shot streams, event streams, and event replies carry the Connection-created Peer.
• Registered the built plugin with a local global 0.2.1-rc.2 installation and verified /ext/bridge-config on port 3080.

Impact

The workspace now pins 0.2.1-rc.2; older DSH versions are not supported by this revision. Chrome/Firefox extension wire messages remain unchanged. Windows installer text is updated, but Windows execution was not tested.
