Ecosystem CI regression: `rslib/modernjs`

Attribution: Confirmed downstream source

Impact: Rslib ecosystem CI now reaches Modern.js's styled-components integration with a Rspack 2.2/SWC 77 host, where all 8 SSR assertions fall back to empty client HTML.

Why this PR

This PR upgrades Modern.js to Rsbuild 2.2.0-rc.0 and correctly moves @swc/plugin-loadable-components to 12.0.0, but leaves @swc/plugin-styled-components at 12.12.1. The former deserialization failures recover, while both streaming and string styled-components SSR paths still fall back with reason: "error"; @swc/plugin-styled-components 13.0.0 is the matching SWC 77 generation. This exposes a downstream WASM-plugin compatibility constraint rather than an Rslib product regression.

Suggested next step

Modern.js should upgrade @swc/plugin-styled-components to 13.0.0 (or another verified SWC-77-compatible build). Verify the focused integration/styled-components suite, then pnpm test --stack rslib modernjs.

Evidence and attribution checks

Current run: https://github.com/rstackjs/rstack-ecosystem-ci/actions/runs/32725202026/job/97424802542
Tested upstream: rslib at af41f2ed7523e2c5130084d80cc058994a628049

Failure signature: one file / 8 styled-components SSR tests fail; generated HTML contains __modern_ssr_fallback_reason__ with reason: "error", no SSR data, and no style tags
Flaky/pre-existing check: the current and first-bad jobs reproduce all 8 failures; the previous job passed all 87 framework files
Config check: active by dependency graph; this PR upgrades Rsbuild to 2.2.0-rc.0 and the failing run executes that graph
Alternatives ruled out: surface Rslib PR refactor: move server plugin logic in cli core #1867 only upgrades @ast-grep/napi; the failure begins when the downstream checkout changes to this PR's merge commit
