Roflin a86aa255f1 Add REVIEW.md: complete hardware-review coverage record
Documents everything examined in the 2026-07-17/18 review - not just
findings but full coverage with verdicts, so future sessions know what
not to re-review: per-sheet verification against datasheets and the
WIZnet reference design, the settled look-wrong-but-correct list
(VPHY/VPLL on 3.3V, D4/D5 floating VBUS + flow-through, EN at 12V,
RSET 12.4k, no CT cap, DO/DI direction evidence), PCB/JLC/BOM audit
state, explicit not-reviewed list (bench/gateware items), and a binding
rule to keep the file updated in the same commit as any change to a
reviewed circuit. Referenced from CLAUDE.md alongside TODO.md.

Roflin fa8fbc35e7 PCB rework: place and route MDI termination + FTDI EEPROM resistors
Rework by Dennis; reviewed with DRC 0 errors / 0 unconnected / 0 parity:
- R26-R29 + C18/C19 at U11's MDI edge (1-3mm from pins), short stubs,
  ETH_DP impedance rules pass, pair skew TX 0.30mm / RX 0.72mm
- D4/D5 true flow-through (PHY side faces U11, cable side faces J2)
- In1 GND plane voided under the magjack cable/isolation side
- R30/R31 placed at U7; 30 GND stitch vias in the ethernet corner
