fix: read react-native shared config from array form of shared

[giaBaoJS]

Summary

ModuleFederationPlugin adds react-native/ and @react-native/ to shared so deep imports resolve through the shared scope, and it copies eager, import (and version in V1) from the user's react-native entry. That copy only works when shared is an object. With the array form, the deep imports always end up as eager: true and without import: false.

Reproduction

new Repack.plugins.ModuleFederationPlugin({
  name: 'miniapp',
  shared: [{ 'react-native': { singleton: true, eager: false, import: false } }],
});

Config handed to the underlying ModuleFederationPlugin:

[
  { 'react-native':  { singleton: true, eager: false, import: false } },
  { 'react-native/':  { singleton: true, eager: true, requiredVersion: '*' } }, // wrong
  { '@react-native/': { singleton: true, eager: true, requiredVersion: '*' } }, // wrong
]

The equivalent object form is handled correctly, which is the sibling path that shows the intended behaviour:

shared: { 'react-native': { singleton: true, eager: false, import: false } }
// -> 'react-native/':  { singleton: true, eager: false, requiredVersion: '*', import: false }
// -> '@react-native/': { singleton: true, eager: false, requiredVersion: '*', import: false }

For a remote container this means the React Native deep imports get eagerly bundled into the container instead of being consumed from the host, which is the opposite of what eager: false, import: false asks for.

Root cause

In the array branch, findSharedDependency returned the array item, which is an object keyed by the dependency name ({ 'react-native': {...} }), rather than the config stored under that key. Reading .eager / .import / .requiredVersion off the wrapper therefore always produced undefined, and sharedDependencyConfig fell back to its defaults. The object branch on the next line returns the config itself, so it never had the problem.

What the tests assert

Four new cases, mirroring the existing object-form tests, two per plugin:

• shared: [{ react: ... }, { 'react-native': { eager: false, ... } }] produces react-native/ and @react-native/ with eager: false (and, for V1, requiredVersion: '0.76.0' rather than '*').
• shared: [{ 'react-native': { import: false } }] produces both deep imports with import: false.

Without the source change all four fail on the value itself (eager is true instead of false, import is undefined instead of false).

packages/repack jest suite: 312 passing before, 316 after, plus tsc --noEmit and biome check clean.
