Foundation for pluggable extension runtimes. One Runtime interface that wazero, v8go, goja, and native-Go all satisfy. Extensions declare their preferred runtime in extension.json; the loader dispatches. This sits alongside plugins/jsvm — goja-via-the-existing-jsvm-path remains the default for .base.js hooks. The new path is for users who want hard-sandboxed WASM extensions or full V8 perf. Files: - plugins/extruntime/extruntime.go — Runtime + Module interfaces, Manifest - plugins/extruntime/manifest.go — JSON manifest loader (stdlib only) - plugins/extruntime/native.go — reference impl, registers Go funcs Concrete runtimes land in sibling commits: - plugins/wasmvm — wazero (pure Go, hard sandbox) - plugins/v8vm — v8go (cgo, -tags v8vm) - plugins/gojavm — goja adapter (no new deps) - plugins/extbench — fixtures + benchmarks across all 5
