fix: honor explicit mfAsyncStartup for containers Allow async startup when mfAsyncStartup is explicitly true, even for chunks with container entries. Only disable async startup for containers when it's implicitly enabled through chunk handlers.

fix(mf): include runtime handlers in enhanced mode Previously, enhanced mode would only set fallback error functions for __webpack_require__.f.consumes, __webpack_require__.f.remotes, and __webpack_require__.I instead of including the actual handler implementations. This caused runtime errors when async startup was enabled. Now enhanced mode includes the actual handler code: - ConsumeSharedRuntimeModule includes consumesCommon.js, consumesInitial.js, and consumesLoading.js - RemoteRuntimeModule includes remotesLoading.js - ShareRuntimeModule includes initializeSharing.js Also adds container entry detection to prevent async startup for container.js files while allowing it for host files (main.js) that consume remotes. Test results improved from 14 failures to 5 failures. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

fix: gate all MF async startup logic on experiment flag Only apply async startup runtime modules when mf_async_startup experiment is explicitly enabled. This prevents adding extra runtime modules to non-MF builds. Fixes test failures where stats snapshots showed 12 runtime modules instead of 3 for regular (non-MF) builds.

fix: properly gate MF async startup to preserve main branch behavior - Separate main branch logic from MF async startup logic - Only apply container entry check to MF async builds, not all builds - Non-MF builds now match main branch (3 runtime modules instead of 12) - Update snapshots for commons-chunk-min-size-Infinity and named-chunks-plugin tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

fix: suppress false positive 'this' unused warning in BuildInfo The TypeScript ESLint rule incorrectly flags 'this' as unused even though it's used via the spread operator (...this) and property accesses. Added eslint-disable comment to suppress this false positive. This unblocks CI which has 2283 warnings vs the 2282 limit. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
