Subject: [PATCH] fix(build): resolve Turbopack performance issue with
 process.cwd()

The Turbopack build was matching 29409+ files due to dynamic path
resolution in upload.ts. This caused the CI build to hang.

Root cause: Turbopack traces process.cwd() and creates overly broad
file patterns, leading to performance issues.

Solution: Extract process.cwd() into a separate function to prevent
Turbopack from tracing the entire project directory.

This fix reduces build time and prevents CI timeout issues.
