Pull request overview

This PR migrates the wit-bindgen-wasm subproject from a wasm-bindgen-style JS module to a WebAssembly Component Model build/output, and updates the VS Code extension’s runtime integration and tests to use the new jco-transpiled API.

Changes:

• Redefines the WIT surface as a component world exporting wit-validator functions (no resource/class instance model).
• Reworks the Rust implementation to use wit_bindgen::generate! + component exports, and updates dependencies accordingly.
• Replaces wasm-pack build steps with a wasm-tools component … + npx jco transpile pipeline; updates TypeScript integration and unit tests.

wit-bindgen-wasm/wit/wit-bindgen.wit	Updates WIT to a component-exported interface/world and adds component extraction functions.
wit-bindgen-wasm/src/lib.rs	Switches Rust exports from wasm-bindgen to component-model exports and refactors binding generation helpers.
wit-bindgen-wasm/create_component.sh	Removes the old component-creation helper script.
wit-bindgen-wasm/Cargo.toml	Drops wasm-bindgen deps and adds wit-bindgen (component bindings) + updates crate descriptions/tooling config.
wit-bindgen-wasm/Cargo.lock	Updates lockfile to reflect new Rust deps and removed wasm-bindgen ecosystem crates.
src/wasmUtils.ts	Updates runtime loading to the jco-transpiled witValidator API (no explicit .wasm initialization via VS Code FS).
tests/wasmUtils.test.ts	Updates mocks/tests to reflect the new module-level witValidator API.
tests/bindings-generation.test.ts	Updates integration-style binding generation tests to use witValidator.generateBindings.
scripts/setup-wasm.sh	Changes setup to focus on wasm-tools + jco availability (instead of wasm-pack).
scripts/build-wasm.sh	Adds a new component build script (core wasm → embed types → component → jco transpile).
package.json	Switches build scripts from wasm-pack to scripts/build-wasm.sh and updates WASM verification target file.
package-lock.json	Removes wasm-pack and its transitive deps from the Node dependency graph.

Pull request overview

This PR migrates the wit-bindgen-wasm subproject from a wasm-bindgen JS-module style interface to a WebAssembly Component Model interface, and updates the extension build/test pipeline to consume the jco-transpiled component API.

Changes:

• Replace wasm-bindgen exports with wit-bindgen component exports derived from wit-bindgen-wasm/wit/wit-bindgen.wit.
• Introduce a new build pipeline (wasm-tools component ... + jco transpile) and update setup/version-sync scripts accordingly.
• Update TypeScript utilities and tests to use the new witValidator API surface.

This PR migrates the wit-bindgen-wasm subproject from a wasm-bindgen JS-focused module to a WebAssembly Component Model build, and updates the VS Code extension to call into the generated witValidator interface (via jco-transpiled bindings).

Changes:

• Replace wasm-bindgen exports with wit-bindgen component exports defined in wit-bindgen.wit.
• Add new component-based build pipeline (wasm-tools component embed/new + jco transpile) and update docs/CI/scripts accordingly.
• Update extension WASM integration and tests to use the new witValidator API shape.
