feat(catalog): list dynamisk-rettsstat v0.1.0

Operator instruction 2026-11-11. The plugin runs the model of the
concept note Den dynamiske rettsstaten on the reader's own numbers;
its skills and documentation are Norwegian. Manifest entry pinned to
the annotated, signed tag v0.1.0, README block, opening line and
PUBLIC_REPOS change in the same commit, as the public-link gate
requires.

NOT TO BE PUSHED before open/dynamisk-rettsstat is public with the tag:
at commit time the repository exists only locally (ktg/ and open/ both
answer 404 with a token), so this entry would be a broken install. The
forge description of this catalog must be set to the new opening line
in the same round; it still reads "Currently Voyage".

Stat line: 4 skills (skills/*/SKILL.md at the tag) and 260 tests
(pytest at the tag); neither is badged, so check-versions names both
as not gated. check-public-links, check-versions (1/1 OK),
check-retired-refs, check-nav-golden, check-okf-parity exit 0; 244 of
244 tests pass.

+### [dynamisk-rettsstat](https://git.fromaitochitta.com/open/dynamisk-rettsstat) `v0.1.0` `🇳🇴 Norwegian`
+
+Runs the model from the Norwegian concept note *Den dynamiske rettsstaten* on your own numbers, by talking to Claude. The model describes the criminal justice chain: where it binds, what kind of measure that calls for, and what happens over time. Skills, examples and documentation are in Norwegian.
+
+- **`diagnose`** — from figures per link (cases in, capacity, backlog) to the link that binds, the type of measure and the capacity needed
+- **`forlop`** — stability check and the month-by-month course of the measure
+- **`simuler`** — from a "what if" question to a scenario file, a run, a table of key figures and a figure
+- **`forbedre`** — a working copy of the model that you own, a map from the note's equations to the code, extensions with a limiting case, and a check that says which of the note's results a change moves
+- **Reproduces the note** — the core is unchanged copies of the note's code, locked by sha256; the check re-creates the note's 22 data files byte for byte with the pinned versions of numpy and scipy
+
+The parameters are stylised and the model is not calibrated on Norwegian data: runs show the model's dynamics, not forecasts. Needs Python 3, plus numpy and scipy for everything except the diagnosis.
