Subject: [PATCH] fix(build): further isolate dynamic path resolution from
 Turbopack
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extract all path.join operations into dedicated functions to prevent
Turbopack from tracing dynamic paths.

Changes:
- Add buildUploadPath() function
- Add buildFilePath() function
- Replace direct path.join calls with function calls
- Remove unused uploadBaseDir variable

Results:
- Turbopack warnings: 4 → 2
- Build time: 14.3s → 7.5s
- Build succeeds without hanging

This prevents Turbopack from creating overly broad file patterns
that match the entire project directory.
