fix(grilling): collapse family to one skill — behavioral test evidence

RED (2026-08-12, clean pi -p subprocesses): user phrases «прогриль мой план»,
«grill my plan», «хватит, точи план», «прогриль с доками» all resolved to
grilling, NOT grill-me/grill-with-docs. Root cause (verified in pi docs
skills.md): disable-model-invocation: true hides a skill from the system
prompt — the thin user-wrapper split (mattpocock's slash-command model) is
structurally unreachable in pi's natural-language matching.

GREEN: single grilling v0.2.0 with integrated Docs mode (trigger «с доками» /
«зафиксируй» → decision record to .wiki/concepts/<topic>-decision.md or
.brainstorm/ append). Re-run: 5/5 positive → grilling, 4/4 negative clean.

Removed grill-me + grill-with-docs (invisible in pi, dead weight); README
table updated; lint 0/0; ~/.claude/skills = 39; dist pruned+rebuilt.
