fix(enhanced): include duplicate shared fallback versions

[2heal1]

What changed

Fixes #4748.

Shared tree-shaking fallback generation now supplements the collected root shared package with all installed versions of that same package from node_modules, including pnpm's .pnpm store layout. Fallback generation then de-duplicates by version so duplicate installed versions can each get a matching fallback artifact.

Why

When a remote used nanoid@3.3.11 through a nested package while the root app had nanoid@5.1.6, the manifest could point to 3.3.11 but only a 5.1.6 fallback was emitted. Runtime then failed because the matching fallback was missing.

Validation

• pnpm exec prettier --check packages/enhanced/src/lib/sharing/tree-shaking/CollectSharedEntryPlugin.ts packages/enhanced/src/lib/sharing/tree-shaking/IndependentSharedPlugin.ts packages/enhanced/test/unit/sharing/tree-shaking/CollectSharedEntryPlugin.test.ts .changeset/green-shared-fallbacks.md
• pnpm --dir packages/enhanced exec rstest test/unit/sharing/tree-shaking/CollectSharedEntryPlugin.test.ts -c rstest.config.ts
• pnpm --filter @module-federation/enhanced run build
• python3.12 .codex/skills/changeset-pr/scripts/run_changeset_status.py --verbose
• git diff --check

I also ran the package lint path through the commit hook. It passed with existing package warnings.

Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.
