Confirm TypeScript PR #60238 changes are already correctly ported

[Copilot]

This PR investigates and confirms that TypeScript PR #60238 "Fix prioritization of paths specifiers over node_modules package specifiers" has already been correctly ported to the Go codebase.

Analysis

The original TypeScript PR #60238 made critical changes to the computeModuleSpecifiers function to ensure that paths specifiers from tsconfig.json are properly prioritized over node_modules package specifiers:

Key Changes:

1. Removed conditional: The getLocalModuleSpecifier call was moved outside the if (!specifier) block to always execute
2. Updated pathsOnly parameter: Changed from modulePath.isRedirect to modulePath.isRedirect || !!specifier
3. Improved prioritization: Ensures paths specifiers are always considered and prioritized over node_modules

Verification

After thorough analysis of the Go implementation in /internal/modulespecifiers/specifiers.go, I confirmed that:

✅ Line 356-364: getLocalModuleSpecifier is called unconditionally (not inside an if block)
✅ Line 363: pathsOnly parameter correctly uses modulePath.IsRedirect || len(specifier) > 0
✅ Lines 365-391: All local specifier processing logic runs unconditionally

Testing

• All existing tests pass without baseline changes
• Build succeeds without errors
• Manual verification confirms paths resolution works correctly with the test case from the original PR
• Repository remains clean with no changes needed

Conclusion

The TypeScript PR #60238 changes have already been correctly ported to the Go codebase. The module specifier prioritization logic properly prioritizes paths specifiers over node_modules package specifiers as intended.

No code changes were required.

Fixes #1127.
