2283178f09 Add Copper ISA Complete Reference Manual 
New file: 08_graphics/copper/copper_reference.md
- Full instruction set reference with opcode encoding table
- Bit-level encoding for MOVE, WAIT, SKIP (7-bit masks)
- Beam position encoding: V counter (8-bit), H counter (7-bit)
- Copper control registers (COP1LC, COP2LC, COPJMP, COPCON, DMACON)
- Copper list structure, dual lists, SKIP-based double buffering
- DMA timing budget calculations per scanline
- Register reference for all copper-writable targets
- OCS/ECS/AGA differences (AGA 24-bit color via BPLCON3 LOCT)
- Programming models: bare metal, OS-friendly UCopList, self-modifying
- Common patterns: rainbow, split screen, status bar, sprite mux
- Debugging: 8 common pitfalls with symptoms and fixes
- Mermaid fetch-execute cycle diagram

Updated files:
- 08_graphics/README.md: add copper_reference.md to index
- 08_graphics/copper/copper.md: cross-reference link, fix MOVE/WAIT
  encoding, fix UCopList CMOVE syntax
- 08_graphics/copper/copper_programming.md: cross-reference link, fix

f61c26b542 Expand documentation suite: 30+ articles enriched with diagrams, code examples, and hardware details 
Graphics: text_fonts (bitmap layout, styles), sprites (DMA, multiplexing), gfx_base (chipset detection), rastport (draw modes, clipping), ham_ehb (mermaid fixes), display_modes (HAM palettes)

Devices: scsi (per-model interfaces, Gayle limits, CD-ROM, native vs vendor drivers), console (ANSI sequences, CON:/RAW:), parallel (CIA registers, pinout), timer (resource exhaustion), gameport (quadrature, XOR state)

Libraries: workbench (WBStartup, AppWindow/Icon/MenuItem), rexxsyslib (ARexx port hosting, command parsing), diskfont (font directory, colour fonts), keymap (rawkey codes, dead keys), locale (catalogue system, date formatting), layers (ClipRect, refresh types), utility (TagItem chains), icon (DiskObject, ToolTypes), iffparse (IFF structure, ByteRun1), expansion (Zorro AutoConfig)

Networking: tcp_ip_stacks (major rewrite - Amiga vs Unix architecture, SANA-II pipeline, PPP/SLIP dial-up, Ethernet cards, MiSTer), bsdsocket (pure API ref), sana2 (buffer hooks, driver requirements), protocols (all code examples). Deduplicated overlap between the three files.

Toolchain: debugging (Enforcer patterns, SnoopDOS, GDB remote, kprintf checklist), sasc (pragma encoding, __saveds idioms), stormc (NEW - StormC IDE, C++, PowerPC)

References: error_codes (DOS, Exec, trackdisk, Intuition error tables)
Driver development: rtg_driver (Native driver analysis, P96 tuning)

All 22 README indexes updated. Root README synced with stormc.md entry.
