Build and Publish Docker Image / deploy (push) Failing after 56s
- Add `WARPBOX_RESUMABLE_CHUNK_MODE` and `WARPBOX_RESUMABLE_CHUNK_PATH` environment variables to configure temporary chunk storage. - Implement strict file validation for resuming uploads to ensure selected files match the pending session's metadata. - Add `PLANS.md` to document development stages, roadmap, and API specifications (including batching and resumable flows).
