copilot-swe-agent[bot]andandrewbranch d85f072ddd Fix: Only allow synthetic defaults for declaration files in export specifiers 
Corrected the fix to only allow synthetic defaults when re-exporting
from declaration files (not TypeScript source files). This aligns with
the issue description which states that declaration files may correspond
to CommonJS modules at runtime where a default import can reference the
whole module.exports symbol.

Only tests targeting .d.ts files should pass without errors:
- reexportMissingDefault4.ts (targets b.d.ts) ✓
- reexportMissingDefault5.ts (targets b.d.ts) ✓

Tests targeting .ts files correctly maintain their errors:
- reexportMissingDefault.ts, 1, 2, 3, 6, 7 (all target b.ts)

copilot-swe-agent[bot]andandrewbranch 7f69f3ca5e Fix: Respect allowSyntheticDefaultImports for export specifiers 
When re-exporting with `export { default as Foo } from "./b"`, the
compiler should respect the `allowSyntheticDefaultImports` option even
for TypeScript source files (not just declaration files).

The fix adds logic in `getTargetofModuleDefault` to allow synthetic
defaults for export specifiers when `allowSyntheticDefaultImports` is
enabled. This is consistent with the intent of the option to allow
treating modules without a default export as if they had one.

Fixes tests:
- reexportMissingDefault.ts
- reexportMissingDefault1.ts
- reexportMissingDefault2.ts
- reexportMissingDefault3.ts
