Thank you!  Cryptsetup is now in my initramfs.  I am close, but there
still remains one issue.  When updating the initramfs, I get:

cryptsetup: WARNING: root target luks.root uses a key file, skipped

But it doesn't use a key file.  My cryptsetup is:
luks.root	UUID=xxx	pwd	luks

And my fstab contains:
/dev/mapper/luks.root	/	btrfs	defaults	0	0

When I boot the system, I drop into initramfs.  There, I can open the
root disk myself and continue the boot process.
