CydandClaude Fable 5 b1753964b2 Hardware docs: board photos, schematic scan, GAL fuse dump ...

Organize the restoration source material under docs/hardware/:
- 9 board photos (renamed from Signal timestamps, index in README)
- Scans_018-014.pdf: 7-sheet VWE schematic set (RIO_1407 CPU/power/IO,
  PBE_1401 buttons, KEY_1402 keypad, DSP_1408 display, AMP_PLT 1413 amp)
- GAL20v8a_5764.JED: fuse map of the 1407's U7 memory decoder

README documents the board family, the 68HC11 memory map decode path,
the pod-bus signal set and jumper addressing, and cross-links PROTOCOL.md
and rio-firmware/.
