feat(wip): integrate scoped SDK and object-centered tools

Vendor the reproducible 1cbe03b4 Client/HTTP/Protocol/Text View snapshot with Cargo checksums and credential-free Nix dependency closure. Migrate native and compatibility publications to structured references and scope_ref, preserve target-first preconditions and frozen call descriptors, and expose Tree/Inspect/Invoke with complete edge coverage and official signatures.

Validation: worker 888 unit + 110 integration tests; pinned upstream Client63, HTTP39, Protocol23, TextView20 tests/doctests; root cargo check --locked --offline; format/diff checks; 43-file vendor checksum verification; nix build --no-link .#yoi.cargoDeps. Details and provider migration seams: docs/development/wip-integration-validation.md.
