compile: Solid "universal" JSX transform for OpenTUI at compile time (moduleName @opentui/solid) + solid-js condition swap #10099

Parent: #10107. Related: #4644 (SolidJS bridge), existing crates/perry-hir/src/solid_jsx.rs.

Problem

OpenCode's TUI is 107 Solid .tsx files (packages/tui/src 99, packages/opencode/src 8) with tsconfig "jsx": "preserve", "jsxImportSource": "@opentui/solid" (packages/tui/tsconfig.json:5-6, packages/opencode/tsconfig.json:5-6). Nothing ships them as JSX:

• The official binary transforms them inside Bun.build with createSolidTransformPlugin() from @opentui/solid/bun-plugin (packages/opencode/script/build.ts:22,174).
• bun run src/index.ts transforms them at load time: packages/opencode/src/plugin/tui/runtime.ts:44 calls ensureRuntimePluginSupport({ additional: keymapRuntimeModules }) → node_modules/@opentui/solid/scripts/runtime-plugin-support-configure.js → ensureSolidTransformPlugin() → Bun.plugin(createSolidTransformPlugin()) (scripts/solid-plugin.js).
  The transform (node_modules/@opentui/solid/scripts/solid-transform.js) is @babel/core.transformAsync(code, { presets: [[babel-preset-solid, { moduleName: "@opentui/solid", generate: "universal" }], [@babel/preset-typescript]] }), i.e. babel-plugin-jsx-dom-expressions in universal mode: elements become createElement(tag) + setProp(el, name, value, prev) inside effect() for dynamic props, children via insert(parent, accessor), components via createComponent(Comp, props) with getters for dynamic props, mergeProps/spread, use: directives, ref, and text via createTextNode — all imported from @opentui/solid.
  The same plugin also rewrites solid-js resolution: onLoad swaps solid-js/dist/server.js → dist/solid.js and solid-js/store/dist/server.js → store.js, because solid-js's node export condition selects the SSR build (non-reactive) while the TUI needs the client build (node_modules/solid-js/package.json exports: node → ./dist/server.js, browser/default → ./dist/solid.js).
  Perry today: perry-hir/src/solid_jsx.rs already implements a "Solid universal JSX expansion" (createComponent/createElement/spread/mergeProps/memo/use), but it is gated by perry.jsx: "solid" in the package's package.json (crates/perry/src/commands/compile/host_config.rs:92) and hard-wires the runtime module name "perry-solid" (collect_modules.rs:668). Without it, perry lowers TSX through its React-style jsx()/jsxs() path, which produces the wrong runtime calls for OpenTUI.

Scope

1. Parametrize lower_solid_jsx on the runtime module name and select it from jsxImportSource in the nearest tsconfig.json (auto) or perry.jsx: { runtime: "@opentui/solid" } (explicit). OpenCode's packages carry no perry key, so auto-detection (or a compile flag) is required.
2. Make the expansion match babel-plugin-jsx-dom-expressions universal output semantically: static vs dynamic prop detection (call/member expressions become effects), children accessors, ref, on* handlers passed as props, use:* directives, spread ordering, fragments → arrays, <For>/<Show>/<Switch> are plain components, text nodes via createTextNode, insert markers. Use the real transform as the oracle: run transformSolidSource(code, { filename, moduleName: "@opentui/solid" }) under bun over all 107 files and compare behaviour (not text).
3. Resolve solid-js and solid-js/store to the client builds (dist/solid.js, dist/store.js) for this graph, mirroring the plugin's onLoad swap (a resolver condition rule or an explicit alias). Verify @opentui/solid itself resolves to the intended condition (index.bun.js under bun, index.js otherwise) and that @opentui/solid/jsx-runtime is not pulled in by the fallback React path.
4. Once compiled ahead of time, the runtime plugin path must become inert (runtime(bun-compat): provide plugin / Bun.plugin as an inert registrar so OpenTUI's runtime-plugin support installs #10100) so @babel/*, babel-preset-solid, browserslist drop out of the live set.

Repro / oracle

• Minimal fixture: an .tsx file importing render from @opentui/solid rendering <box><text>{count()}</text><For each={items()}>{(i) => <text>{i}</text>}</For></box> with a createSignal update; compare frames from @opentui/core test renderer under bun vs the perry binary.
• Full: packages/opencode/src/cli/tui/worker.ts + packages/tui/src/** render the first TUI frame under the native binary.

Acceptance

• All 107 OpenCode .tsx files compile with the universal transform; no jsx()/jsxs() React-runtime calls remain in the emitted HIR for those files.
• Fixture frames identical to bun for static props, dynamic props, children accessors, components with getters, ref, use: directive, spread.
• solid-js resolves to dist/solid.js (reactive) in the OpenCode graph; a test asserts createSignal updates re-render.
• TUI first frame renders from the native binary (with runtime(bun-compat): provide plugin / Bun.plugin as an inert registrar so OpenTUI's runtime-plugin support installs #10100, 03, 05).
