CC Support Window — Floor Bump to 2.1.148

The single source of truth is supported_floor in cc-support.json; stamp-cc-support.mjs propagates it to MIN_CC_VERSION, CLAUDE.md, and the doctor doc, and a STRICT test requires every SKILL.md floor ≥ it. Drag the floor to see who's dropped and what the derived files become. #1945 sets it to 2.1.148 (the Bash exit-127 correctness fix).
