docs: streams upgraded to in-scope (operator-authority record)

The inventory graded streams absent because no paused consumer document
names it; the operator correction: type-filtered event watching from
several places (e.g. repo-change subscriptions in a git app at
gitea/gitlab scale) is a basic reactivity requirement — and notify
(fire-and-forget, no replay) cannot serve subscriptions honestly.
The wanters are applications above the paused crates, which is why the
docs don't carry the row.

Inventory: streams row recorded on operator authority (the REQ-2
recording convention from alkblobs requirements.md), confidence system
gains the operator-authority grade; rate-limits becomes the sole
first-cut candidate. phase-0: OQ-ST-01 summary and OQ-ST-04's
contract-candidates updated to match.

+subscription must survive the subscriber being offline at event time
+(durable log + per-consumer offset + replay-on-attach is exactly
+honker's stream model). Why the paused docs missed it: the consumers
+that want it (a git app's subscription surface, cross-app event
+watching) are *applications above* the current paused crates, so
+nothing written down yet carries the row — which is expected, not
+suspicious. Design note for OQ-ST-04: on the Postgres side this is a
