From 263f63bec8cfdaf2116f907d965e9cc3b08b1817 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Trait-aware frontend: samlingssider med dynamiske
 trait-paneler (oppgave 13.2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Samlingsnoder med `metadata.traits` rendres nå som egne sider på
/collection/[id]. Hvert trait-navn mappes til en dedikert Svelte-komponent
som viser relevant UI. Traits uten egen komponent vises med et generisk panel.

Komponenter for 9 traits: editor, chat, kanban, podcast, publishing,
rss, calendar, recording, transcription. Mottak-siden viser traits som
pills og lenker til samlingssiden.

 - [x] 13.1 Trait-metadata på samlingsnoder: maskinrommet validerer `metadata.traits`-objektet ved `create_node` og `update_node` for samlingsnoder. Avvis ukjente trait-navn. Ref: `docs/primitiver/traits.md`.

+- [x] 13.2 Trait-aware frontend: samlingssider leser `traits` fra metadata og rendrer kun aktive komponenter. Dynamisk komponent-lasting basert på trait-liste.
 - [ ] 13.3 Pakkevelger: UI for å opprette ny samling med forhåndsdefinert pakke (nettmagasin, podcaststudio, redaksjon osv.) eller manuelt valg av traits.
 - [ ] 13.4 Trait-administrasjon: admin-UI for å legge til/fjerne traits på eksisterende samlinger med konfigurasjon per trait.
