docs: correct false lithoglyph tombstone (no lith monorepo) (#44)

The `lithoglyph/MOVED.md` falsely announced a move to a `lith` monorepo.
**Owner-disavowed** — that consolidation was never authorised and
`hyperpolymath/lith` does not exist; the content (73 entries) still
lives in `nextgen-databases/lithoglyph/`.

This corrects the tombstone to the truth: extraction is **planned, not
done**, into the now-reserved repos `lithoglyphdb` / `gnpl` /
`glyphbase`. Stops the file misleading future readers/agents.

+= Lithoglyph — extraction PLANNED (not yet moved)
 
-**Lith core is now part of the [Lith monorepo](https://github.com/hyperpolymath/lith).**
+The Lithoglyph stack still lives *here*, in `nextgen-databases/lithoglyph/`. Treat
+this directory as canonical until migration completes.
 
-## New Location
+Planned standalone repositories (reserved 2026-06-22; migration pending):
 
-- **Monorepo:** https://github.com/hyperpolymath/lith
-- **Database Core:** https://github.com/hyperpolymath/lith/tree/main/database
+* Database core -> https://github.com/hyperpolymath/lithoglyphdb
+* Query language (GNPL / GQL-dt) -> https://github.com/hyperpolymath/gnpl
+* Airtable-mode delivery -> https://github.com/hyperpolymath/glyphbase

-All Lith development now happens in the monorepo for better coordination and discoverability.

+CAUTION: a previous version of this file claimed the code had moved to a `lith`
+monorepo. That was INCORRECT — no such consolidation was authorised and no
+`lith` repo exists. The move has not happened yet.
