micheleandClaude Sonnet 5 e7f9b9f719 docs: add real BOM, flag FPGA grade discrepancy (8BG381I vs 8BG381C) ...

Real KiCad-exported BOM added to the hardware chapter, cross-checked
against every component value this chapter already specifies -- most
match exactly (R1/R2 feedback divider, L1/L2, ferrite part number, all
three real ICs). One real discrepancy found: U2 is captured as
LFE5U-45F-8BG381I (industrial grade) while every other reference in
this project uses the C (commercial) grade part -- flagged, not
resolved, needs explicit confirmation.

Also resolves three earlier open items from the schematic review:
R3=499k confirms TLV62568's EN is populated; R5-R12 being 8 discrete
0402 resistors (not a multi-resistor array) confirms the JTAG
pull-up/down polarity concern doesn't apply; U5 confirms the
previously-missing 16MHz oscillator is now present.

Compiled clean (47 pages, 0 errors).
