Owner's reorganisation: frame into 2009-fpga, media regrouped, old math versions removed

- original-frame/ moves into 2009-fpga/original-frame/ (the FPGA version introduced the frame).
- Media regrouped by the owner: the two 2011-07-01 PNGs and MOV02256-02259 to FireFly, SNC00198.jpg to the FPGA version.
- Removed from the current version (still in the history): docs/math wisFORlive.docx, wisFORlive3.docx, wisFORlive4.docx and 'z axis rotation.url'.
- READMEs, 2026-current/CLAUDE.md and the root timeline updated to match.
