docs: bring CURRENT_STATE up to date with 0.4.3 and the scenario corpus work

The living document drifted through two paths that bypass a normal feature PR:
the release PR is created by the changesets action and never touches this file,
and issue-only work leaves no PR at all.

Records the 0.4.3 release, and the 0.3.2 release from 2026-07-14 that was never
logged either. Corrects the package status table, which had said 0.3.1 since
the v0.4.0 release.

Adds a section covering the external contribution pipeline: the second
good-first-issue completing, the patch-not-minor changeset decision, the
detection-rule coverage audit that found 3 of 16 rules with no scenario, the
three issues opened to close it, the retarget of #108, and the station ID
allocation.

Also corrects an overclaim introduced in #135. PR #133 was described as the
first external contribution to a good-first-issue. It is the second: #105 was
labelled good-first-issue and Develop-KIM completed it in #114, shipped in
0.3.1.

Notes the open design questions on #144 under pending decisions, which had
claimed nothing was outstanding.

Closes #145

+
+- ✅ Second `good-first-issue` completed by an outside contributor: #133 for
+  #104, shipped in `0.4.3`. The scenario registry is at 16. Two of the five
+  original good-first-issues have now been completed, by two different people.
+- ✅ Scenario changesets sized as `patch`, not `minor` (Issue #142, PR #143).
+  The changeset from #133 was a minor, which would have spent `0.5.0` on one
+  scenario and pushed OCPP 2.0.1 to `0.6.0`. The convention is now written into
+  `CONTRIBUTING.md`.
+- ✅ Detection-rule coverage audited: 13 of 16 rules had a scenario.
+  `TIMEOUT_NO_HEARTBEAT`, `FIRMWARE_UPDATE_FAILURE` and
+  `REPEATED_BOOT_NOTIFICATION` had none.
+- ✅ Three good-first-issues opened to close that gap (#137, #138, #139), each
+  with its full trace specified and checked against the detection engine before
+  publishing, so the specs are known to fire exactly one rule.
+- ✅ #108 (`meter-value-zero`) retargeted as a negative control. Its original
+  `expectedFailures: ['METER_VALUE_ANOMALY']` could not hold: that rule fires
+  only on negative or decreasing cumulative readings, and a flat series is
+  neither.
+- ✅ Station IDs allocated per issue so parallel work cannot collide:
+  `CS-SYNTHETIC-016` shipped in #133, `017` to #108, `018` to #137, `019` to
+  #138, `020` to #139.
+- 🔜 #140 proposes the standing invariant that every detection rule ships with a
+  scenario in the same PR, which is what stops this gap reopening.
+- 🔜 #144 proposes a `METER_VALUE_STUCK` rule for a register that never advances,
+  the positive counterpart to #108.
+
+Scenario arithmetic to the v1.0 target of 20+: 16 today, plus #108, #137, #138
+and #139 lands at 20, at which point all 16 detection rules are covered.

 ## Known Blockers / Decisions Pending
 
-- None currently. All design decisions resolved in ADRs.
+- Nothing is blocked. One design question is open: #144 (`METER_VALUE_STUCK`)
+  needs decisions on what counts as stuck, how to avoid reporting legitimate
+  `SuspendedEV` / `SuspendedEVSE` flatlines, whether a register stuck at zero is
+  a separate signal from one stuck at a non-zero value, and severity. It most
