Test Plan

I verified the path fix by running a full build of the base image for finrl_env. Since the previous COPY path was broken, the build used to fail at step 3. With this fix, it completes successfully.

Command: docker build -t envtorch-base:latest -f ./src/openenv/core/containers/images/Dockerfile .

Greptile Summary

Fixed broken COPY path in base Dockerfile from non-existent src/core/pyproject.toml to correct pyproject.toml at repository root.

• Path change corrects build failure at step 3 where COPY command couldn't find source files
• Comment on line 14 still references outdated Dockerfile path and should be updated
• No architectural changes, invariants, or security concerns

Confidence Score: 5/5

• Safe to merge - straightforward bug fix with verified path correction
• Simple path fix in Dockerfile correcting a broken COPY command. Author verified fix by successfully building the image. Only issue is an outdated comment reference.
• No files require special attention - single-line fix is correct
