micheleandClaude Sonnet 5 58b7374106 docs: real KiCad schematic review + reserved PCB module section

Adds a dated review section recording today's actual schematic check
against every real ball assignment in this chapter: confirmed-correct
items, two real findings needing correction (boot-flash net-name
mismatch FGPA/FPGA typo + SCLK/CLK label mismatch that would leave the
flash electrically disconnected from the ECP5's config engine; SDRAM
CAS#/WE# appearing swapped vs. the verified F7/F9 assignment), and
open items not resolvable from the schematic image alone (regulator EN
pins, a stray +1V1 label near the VCCAUX ferrite, JTAG pull-up/down
array polarity).

Also reserves a "PCB module form factor" section (castellated-edge SMD
module, ~50x25mm) for the future physical layout.

Compiled clean (46 pages, 0 errors).

Nota sul pinout

Il capitolo Progetto hardware e mappa dei segnali riporta l'analisi completa segnale-per-segnale del top-level spi_neuron_top, con la colonna Ball compilata con assegnazioni CABGA381 reali (53 segnali, .lpf reale in synth/) e verificata da un place&route reale (nextpnr-ecp5, 0 errori di vincolo, Program finished normally) — non più auto-piazzate.
