gui-v0.4.41

Expert mode, part two: the rest of the manual-override set, same "extend the
Advanced panel" pattern as 0.4.40's kext overrides.

• SSDT overrides — --exclude-ssdt NAME (repeatable) drops a precompiled
  SSDT ocforge would otherwise add, e.g. --exclude-ssdt SSDT-PLUG. No
  --include-ssdt: an arbitrary SSDT name doesn't map onto a real Dortania
  asset the way a kext name maps onto a real kext, so adding one ocforge
  doesn't know about still means supplying the .aml yourself.
• SMBIOS override — --smbios MODEL (e.g. iMac19,1) replaces ocforge's
  own board-generation pick. Checked for the right shape up front; macserial
  is the real authority and fails loudly if the model doesn't exist.
• Quirk overrides — --quirk NAME=true|false (repeatable) flips one
  ACPI/Booter/Kernel/UEFI Quirks toggle directly. On/off toggles only — the
  handful of numeric Quirks entries (a slide count, a timeout) are rejected
  rather than silently coerced. build/offline-installer only, since
  there's no config.plist to apply a quirk to at plan/explain time.
• All three get matching fields in the GUI's Advanced panel, and — like the
  kext overrides before them — an override adds a warning to ocforge plan's output so it's clear which parts of the build were manual.
