feat(search): add cpu subcommand and wide mode to brev search

Restructure `brev search` into gpu/cpu subcommands:
- `brev search` / `brev search gpu` - GPU instances (default, backwards compatible)
- `brev search gpu --wide` - GPU instances with RAM and ARCH columns
- `brev search cpu` - CPU-only instances via ?include_cpu=true API param

CPU search has dedicated columns (TYPE, PROVIDER, VCPUs, RAM, ARCH, DISK,
$/GB/MO, BOOT, FEATURES, $/HR) and filters (--min-ram, --arch).

Shared filters (--provider, --min-vcpu, --min-disk, --max-boot-time,
--stoppable, --rebootable, --flex-ports, --sort) work across both modes.

Piping into `brev create` works for both GPU and CPU table output.
