job4: SPEC-09 retire-real-state-snapshot

Deleted T4e + its coupled echo note in lib/tests/run-reconcile.sh and
the fixtures/real-state.snapshot it read — superseded by SPEC-08's T7,
which actually DRIVES the tree_clean/pushed/msg_committed oracles
instead of miming them via a static line-count regex. Closes J4-09
(WEAK+drift): T4e only counted fixture line-suffixes matching
`=(true|resolved|present)$`; the snapshot itself was stale
(BLK-009=open contradicted blockers-snapshot.md's already-resolved
status) and unowned, and the drift was inert (`=open` doesn't even
match the count regex) — the assertion could never have caught
anything.

Updated skills/reconcile/SKILL.md:53's hardcoded "20/20" claim to the
new total (unguarded file, same logical step, ordered after SPEC-08+
SPEC-10 per the report).

grep -c 'real-state.snapshot' lib/tests/run-reconcile.sh == 0
(verified). No red demo (deletion, per spec) — gate is the green run
+ that grep. GREEN: 25/25 passed, shellcheck clean.
