Rook native owners cb428bc878a9

Coordinated immutable preview for Rook, from cb428bc.

Includes native browser worker supervision, actor-tree placement and full-event activity, Chrome Port sockets, whole-pool SQLite snapshots, Shell native-directory/workspace primitives, Codemode schema printing and emitting-socket React identity. Intentional worker deletion preserves close code 1001 and retires disconnected transports before removing storage.

Source: #105 (stacked on #104). Consumer: WebMCP-org/rook#216 (stacked on #205).

The runtime archive was rebuilt from this exact commit. The five SDK archives are byte-identical to the previous preview: their source tree is unchanged at this commit and their full maintained suite passed 3,935 tests. Source and declarations remain aligned; SHA256SUMS covers all six archives.

Verified 1,063 native unit tests, runtime/conformance/example types and the packed export/type gate. Full prior CI passed 429 conformance cases and 109 real-example assertions; fresh CI runs on the linked pull request.
