FABRIC-3.md: version correction -- LITHOS_VERSION back to 2.0.0, plus a rename-gap fix

LITHOS_VERSION 2.0.1 was premature: per this project's own versioning
policy, 2.0.1 claims SER5 hardware-track progress (RDRAND backend +
thumbdrive image) that was never actually verified on real hardware --
that verification is FABRIC-3.md's own open topic. Reset to 2.0.0
(still a QEMU-only release, correctly). Verified 3-arch boot shows
"LithosAnanke v2.0.0" in each serial log directly, not assumed from the
Makefile edit alone.

Also closes a real gap found in today's earlier FABRIC-series rename:
Makefile.starkernel, Kconfig.kernel, scripts/bleach_zuse_img.sh, four
proof/*.thy files, and isr.S were never swept -- the original file list
only matched *.md/*.c/*.h/*.4th, silently skipping every other
extension. Fixed with the same safe placeholder substitution.
.claude/settings.local.json's historical permission-grant log and
ClaudeEXPORT/'s frozen export were deliberately left untouched.
