* fix: dedup RSC client references to prevent module duplication in dev

When the RSC plugin creates client-in-server-package-proxy modules for
"use client" submodules within packages, it re-exports from absolute
file paths. These bypass Vite's pre-bundling in the client environment,
causing the browser to load two separate module instances — one from the
raw ESM path and one from .vite/deps/. This breaks React context
providers/consumers since createContext() runs twice.

Add vinext:client-reference-dedup plugin that intercepts absolute
node_modules path imports originating from proxy virtual modules in the
client environment and redirects them through bare specifier imports,
which Vite's import analysis routes through pre-bundling automatically.

Closes #409

* fix: make dedup test layout a server component to exercise RSC proxy path

Remove "use client" from layout.tsx so ThemeProvider import goes through
RSC → client-in-server-package-proxy (absolute path), while the page's
useTheme goes through client pre-bundling (bare specifier). This ensures
the integration test actually validates the dedup plugin works.

* docs: address PR review feedback for client-reference-dedup plugin

- Document lossy submodule-to-package mapping assumption in resolveId
- Extract load filter regex to named DEDUP_FILTER constant
- Note default export edge case in generated re-export code
