Revised approach: submodule stays as default, added context.yaml override for users with rc-context elsewhere. shape.py resolution: context.yaml path → context/rc-context/ submodule → empty. Removed old cross-workspace hardcoded paths and unused RC_CONTEXT_DIR constant. context.yaml is gitignored, context.yaml.example checked in. Commits: bdbc177 (submodule), 60a8ee3 (configurable path).
