feat(runtime): add weft-runtime crate skeleton New crate: weft-runtime — the child process spawned by weft-appd to execute WEFT application packages. src/main.rs: - Parses CLI arguments: <app_id> <session_id> (as per the supervisor contract in runtime.rs). - resolve_package(): searches user store (~/.local/share/weft/apps/<app_id>) then system store (/usr/share/weft/apps/<app_id>) for a wapp.toml manifest. Overridden by WEFT_APP_STORE env var. - Verifies app.wasm exists in the resolved package directory. - Stubs Wasmtime execution with a TODO comment; prints 'READY' to stdout and exits cleanly so weft-appd's supervisor can complete the session lifecycle during development and integration testing. Tests (2): - package_store_roots_includes_system_path: system store path present. - package_store_roots_uses_weft_app_store_when_set: WEFT_APP_STORE override replaces default search list. Also: - Added weft-runtime to workspace Cargo.toml members. - wsl-test.sh: added cargo test -p weft-runtime. 2026-03-11 08:27:30 +00:00			`[package]`

feat(runtime): add wasmtime-runtime feature gate for real Wasm execution Cargo.toml: - New feature: wasmtime-runtime = [dep:wasmtime, dep:wasmtime-wasi] - Default is off so the normal build remains lightweight. - wasmtime 30 and wasmtime-wasi 30 added as optional dependencies. src/main.rs: - run_module(wasm_path) replaces the inline stub. - cfg(not(feature = wasmtime-runtime)): prints READY and returns. Preserves all existing test and development behaviour unchanged. - cfg(feature = wasmtime-runtime): creates a Wasmtime Engine + Module, builds a WASI linker with inherited stdout/stderr, prints READY, then instantiates the module and calls _start. READY is printed before _start so weft-appd can record the session as Running before the app enters its event loop. The production service binary is built with: cargo build -p weft-runtime --release --features wasmtime-runtime 2026-03-11 09:26:41 +00:00			`[features]`
