Adds .agents/skills/data-driven-design: general mechanisms in code, all specific knowledge in data. Written for the long-term cleanup that would let sow-tools be open sourced.

Grounded in two real failures: the value_encodings mode zoo (per-column mode enums + switch arms where a shape/encoding declaration in data would do) and the skills dataset rename (code hardcoding dataset names/key prefixes that the data already knows).

Tested per TDD-for-skills: a baseline subagent given the EquipSlots scenario added a fourth mode and rationalized it ("three switch cases isn't a pattern crisis"); with the skill loaded it declared shape in data, collapsed the modes into orthogonal primitives, and deleted the switch.

Pattern skill for keeping specific knowledge (dataset names, column
encodings, layout) in data and only general mechanisms in code — the
direction sow-tools must move to be open-sourceable. Grounded in the
value_encodings mode zoo and the skills-dataset rename breakage;
baseline-tested against a subagent that reproduced both failures.
