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.

 # 2011–2012: FireFly (Arduino Mega + SSC-32)
 
 In June 2011 the robot was rebuilt around an Arduino Mega 2560 and a Lynxmotion SSC-32 servo controller,

 `#n Pxxxx Txxx` commands to the SSC-32 over `Serial1` at 38400 baud. The serial banner calls it "FireFly".
