Phase 1 continued: serial, input devices + README indexes

Browse source 
10_devices:
- serial.md: expanded with DB-25 pinout, custom chip UART registers,
  baud rate calculation table, open/configure/read/write patterns,
  serial debugging (KPrintF/Sushi)
- input.md: expanded with handler chain architecture diagram,
  InputEvent struct, event classes table, qualifier bits, custom
  handler with key remapping, event consumption/blocking,
  synthetic event injection, Commodities Exchange

Updated indexes:
- 07_dos/README.md — enriched descriptions for all files
- 10_devices/README.md — enriched descriptions for all files

# Devices — Overview
Amiga devices are shared libraries with an exec I/O request interface. They provide standardised access to hardware peripherals via `OpenDevice`/`CloseDevice` and `DoIO`/`SendIO` patterns.
