- Remove the Zig `agent-native` git submodule (no Rust crate depends on it;
the built-in agent runtime is the Rust `agent` crate under vendor/agent).
- Make the repo root a pure Cargo workspace: delete root package.json + bun.lock;
move all web-SDK JS/Bun tooling into packages/ (new packages/package.json
workspace root, generate-iconify-catalog.mjs, and the oxlint/oxfmt configs).
- Scrub agent-native from all docs and fix README dev commands + prerequisites
to reflect the Rust product (cargo directly; bun tooling runs from packages/).
- Drop the deleted-root-package.json read from the op-host-web ci_workflow test.
