fix(enhanced): preserve same-version shared modules across scopes

[ScriptedAlchemy]

Description

Keep same-version shared providers separate when they use different scalar share scopes. For example, React 1.0.0 in scopes a and b now registers both factories and emits separate rows with the correct assets and options. Previously, deduplication could discard one registration while local fallbacks masked the loss. Preserve requiredVersion: false and match configured aliases to their owning scope/layer.

Related Issue

Stacked on layers PR #5039 (feat/rspack-layered-shared-metadata), which builds on graph foundation #5080. Provider metadata is outside this stack: see RFC #5082 and independent draft #5083.

• I have updated the documentation.

Validation: the real Webpack fixture covers unlayered and common-layer providers, checks registration with a separate consumer without fallbacks, and verifies exact stats/manifest rows and assets. It passes within the 18 related layer config cases. The inherited runtime fix passes 141 runtime-core, 70 SDK (one existing skip), and 103 bundler tests, plus 26 compatibility assertions with actual Federation 0.24.1/2.9.1 constructors. Normal hooks and affected dependency builds passed. The earlier ee3f65a runtime head passed hosted formatting, builds, publishing checks, affected tests, and Node.js 20 verification. Final-head validation is tracked below; unrelated full app suites were not rerun.

The compiler compatibility fixture pins Rspack 1.3.9/Federation 0.13.1 as the older host and the published final Rspack d538c9c preview (2.2.7) with the current workspace runtime as the remote. All four old-host cases pass locally across default/custom scopes and remote-entry/manifest loading. The complete manifest suite passes 55/55 tests. The final published c4521e5 Federation suite (2.9.2) passes four actual native same-scope/key/version layer cases, both provider orders and eager/lazy loading, plus four sync/async adapter cases, 26 assertions with actual Federation 0.24.1/2.9.1, and two classic share-entry checks. Both Linux x64 and Mac ARM64 compiler preview workflows succeeded. Both final core heads pass hosted formatting, package builds, publishing checks, and affected package tests; Node.js 20 also passes on both heads; broader E2E jobs remain pending. The two shared preview checksums were refreshed after the Mac publication; an empty-store frozen installation verifies the compiler, wrapper, and Linux binary.

Two sync/async regressions cover compiler-provided share entries without enhanced shareConfig. The seven formerly failing legacy config cases and two provider cases pass locally after the one-line compatibility fix.
