Subject: [PATCH 1/2] Return default_version to stable now that 1.0.0 has
 shipped

1.0.0 is tagged and dist'd (RELEASE.md step 6, done outside this PR - make tag
pushes to origin, which is a personal fork in this checkout, so the tag was
created and pushed to upstream manually instead). This is step 7: flip
default_version back to stable so ordinary source edits regenerate
sql/count_nulls--stable.sql instead of silently corrupting the just-released
sql/count_nulls--1.0.0.sql, add the update script from 1.0.0 to stable, and
open a fresh stable section in HISTORY.md for the next cycle. Verified:
make verify-results green, and the full update chain (CREATE EXTENSION VERSION
'0.9.6' -> ALTER EXTENSION UPDATE -> stable) still works end to end.

Also keeps sql/count_nulls--1.0.0.sql installable going forward (a manual
DATA += in the Makefile) since it drops out of base.mk's install-script
wildcard once it's no longer the "current version" file - the same gap
already tracked as Postgres-Extensions/pgxntool#48.
