fix: handle excluded shared keys and scoped remote names in dev bootstrap

[Staremang]

Bug 1: generateMFManifest crashes on shared keys removed by excludeSharedSubDependencies

The new excludeSharedSubDependencies (dev mode only) deletes a shared key from options.shared if it is a dependency of another shared package. But the key may already be in usedShares (added earlier by createEarlyVirtualModulesPlugin, enforce: "pre"). When /mf-manifest.json is requested, generateMFManifest iterates usedShares, calls getNormalizeShareItem(key) (returns undefined), then crashes on shareItem.version. Dev server responds 500 and the host fails with RUNTIME-003: Failed to get manifest.

generateLocalSharedImportMap in the same file already guards against this — generateMFManifest was missing the same check.

Repro: share two packages where one is listed as a dependency of the other (e.g. @scope/components deps include @scope/utils, both shared).

Fix in src/plugins/pluginMFManifest.ts: switch .map() to .flatMap() and skip entries with no shareItem.

Bug 2: Scoped remote names break the auto-preload bootstrap

pluginAddEntry.ts builds the host bootstrap with:

.filter((remote) => remote.includes('/'))

intending to keep only sub-path entries (e.g. remote/App) and skip bare container names (remote). For scoped remotes like @scope/remote, the / from the scope makes the bare name pass the filter. The generated bootstrap then calls runtime.loadRemote("@scope/remote") with no exposed path, which is translated into module . and fails with Module . does not exist in container. The host never boots.

Repro: any host with a scoped remote (@scope/remote) where the remote only declares sub-path exposes (no '.').

Fix in src/plugins/pluginAddEntry.ts: compare against the remote key instead of using the / heuristic.

const remotePreloads = Object.entries(getUsedRemotesMap())
  .flatMap(([remoteKey, remotes]) =>
    Array.from(remotes).filter((remote) => remote !== remoteKey)
  )
  .sort()
  .map((remote) => `runtime.loadRemote(${JSON.stringify(remote)})`)
  .join(',');
