v0.2.0

Added

• thinking-map skill. Castra governs how work ends; this covers how it starts.
  Four stages: split the subject into orthogonal axes before writing any candidate,
  spread at least four per axis with the last one an inversion, cross-link items from
  different axes with a written mechanism per pair, then prune against a criterion
  fixed in advance. Two rules do the work — the orthogonality test that keeps axes
  from collapsing, and the mechanism sentence that separates a synthesis from a list
  pretending to be one. English and Korean versions ship together.
• The installer places the skill in ~/.claude/skills/thinking-map/ and leaves an
  existing skill of that name untouched.
