docs(amiga): add Tier 4 content — AHI, cross-compilation, RTG, demoscene section

- New: 11_libraries/ahi_programming.md — AHI retargetable audio API
- New: 13_toolchain/cross_compilation_guide.md — cross-compiling for Amiga
- New: 08_graphics/rtg_programming.md — RTG Picasso96/CyberGraphX programming
- New: 17_demoscene/ — full demoscene techniques section:
  - copper_effects.md (6 techniques, 10 Pouet screenshots, antipatterns)
  - sprite_techniques.md (5 techniques, antipatterns)
  - pixel_tricks.md (5 techniques, antipatterns)
  - 3d_rendering.md (fixed-point math, 4 techniques, antipatterns)
  - timing_optimization.md (7 techniques, instruction timing tables)
  - README.md (section index with Mermaid diagrams)
  - images/ (10 authentic Amiga screenshots from Pouet.net)
- New: 05_reversing/games/ (4 copper-analysis screenshots)
- Updated: README index, TODO status (30/30 complete)
- Added external references: Pouet/Demozoo links, Scoopex YouTube
  tutorial series, Amiga Graphics Archive, coppershade.org
