fix: handle missing package.json in copyDependenciesInMemory for S3 storage

https://sonarly.com/issue/24354?type=bug

Logic functions fail to execute when using S3 storage with LOGIC_FUNCTION_TYPE=LOCAL because `copyDependenciesInMemory` unconditionally tries to download `package.json` from S3 without checking if it exists first, throwing FILE_NOT_FOUND.

Fix: Added a `checkFileExists` guard for `package.json` in `copyDependenciesInMemory`, matching the existing pattern already used for `yarn.lock` in the same method.

**Before:** `package.json` was unconditionally downloaded from S3 storage. If the file didn't exist (e.g., workspace created before v1.17 backfill, or failed upload during workspace creation), the S3 driver threw `FileStorageException: File not found`, crashing logic function execution.

**After:** Both `package.json` and `yarn.lock` existence checks are parallelized via `Promise.all`. If `package.json` doesn't exist in storage, a minimal default is written locally (matching the pattern already used for missing `yarn.lock`). This allows logic function execution to proceed gracefully.

The fix is intentionally minimal — it only changes the internal resilience of `copyDependenciesInMemory` without modifying the method signature, so the two callers (`local.driver.ts` and `lambda.driver.ts`) require no changes.
