Jaskiniowy-Kataster-Tatr-Zachodnich

Add a new cave to the Jaskiniowy Kataster Tatr Zachodnich project. Creates the full directory structure, SRV files, _RAW/ folder, and KATASTER.wpj entry.

Verify that a refactor did not lose cave data. Two modes — (a) single cave HEAD vs WIP for a local refactor, (b) whole project current-branch vs master for a branch-level refactor (e.g. OTWORY GPS render).
