Code Review
This pull request modifies the ExternalsResolver to stop externalizing ESM-only packages and packages with the @eggjs/ prefix, as Turbopack is capable of bundling ESM natively. The isEsmOnly and hasRequireCondition helper methods were removed as they are no longer needed. One review comment identifies a redundant check for the 'egg' package name, which is already included in a set of always-external names.

The check if (name === 'egg') return true; is redundant because 'egg' is already included in the ALWAYS_EXTERNAL_NAMES set (defined on line 21), which is checked on line 65.

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
Enables bundling of Egg framework packages by removing @eggjs/* from the auto-externalization rules and adjusting resolver behavior/tests accordingly.
Changes:
- Removed
@eggjs/*name-based externalization inExternalsResolver. - Dropped the ESM-only externalization logic (and removed the related private methods).
- Updated
ExternalsResolvertests to assert@eggjs/*and pure-ESM packages are no longer externalized.

Removes
@eggjs/*fromExternalsResolver's always-external list and thestartsWith('@eggjs/')check. Keeps native addon/ESM-only/peerDeps detection intact. Also cleans up the dead#isEsmOnlyand#hasRequireConditionprivate methods (fixes typecheck error present in #5863). Flips ExternalsResolver test assertions accordingly.Result: framework packages can now be bundled. cnpmcore E2E externals 76 → 12.
Part of #5863 split. Tracking: #5871.
