fix(udgaver): porten dækkede 29 ruter og skulle dække 63 — og fladen ringede stadig på dørene

Prøven, der skal holde udgaverne adskilt, stod grøn gennem to merges, mens
34 opgaveruter blev betjent af noter-udgaven. Den fejlede ikke: den
sammenligner routeren med en nedskreven liste, og listen var skrevet ud
fra de ruter, nogen havde tænkt på. Den er en DRIFT-kontrol, og den kan
ikke være en fuldstændighedskontrol. Det står nu i prøven selv.

Lukket: CalDAV-træet (8 ruter, alle læser eller skriver en VTODO),
.well-known/caldav (en påstand om at der er en CalDAV-server), ICS-feedet
og de to ruter til dets token, de fire opgave-eksporter, Todoist- og
CSV-importen, skabelonerne, sektionerne, de seks AI-opgaveruter og
indbakke-krogen. Plus fem af ni MCP-værktøjer — endepunktet er der
stadig, værktøjslisten er kortere.

Tre blev afgjort ved at læse frem for ved navnet: en skabelon laver
opgaver (CreateProjectFromTemplate), `section_id` står på `tasks` og
findes ikke på `notes`, og add_comment hænger på en opgave.

Men den dyre halvdel var fladen. En vandring gennem hver side, der kan
nås i noter-udgaven, med konsollen og svarene aflæst, fandt SYV brud —
fire af dem fra den første port:

  sidebjælken      GET /filters  404 ved hver navigation, ædt af .catch()
  sidebjælken      GET /labels   404 ved hver navigation, ædt af .catch()
  notifikationer   GET /ai/plan  404, stille
  notesbogens side GET /tasks    kastede → status = 'failed'
  notesbogens side GET /sections kastede → samme fejlskærm
  indstillinger    GET /templates  toast med fejlbesked på skærmen
  integrationer    GET /feed     404, stille

Den fjerde er den, der har kostet noget: /projekt/{id} er notesbogens
side, og kaldene samles i et Promise.all, så én 404 tog hele siden med.
Den har vist en fejlskærm frem for noter siden porten blev sat. Ingen
prøve åbnede en notesbog i den udgave, og .catch(() => {}) sørgede for,
at resten ikke sagde noget. "Fladen følger udgaven" var sandt om menuen
og falsk om hentningerne.

Vagten for opgaver står i butikken frem for ved kaldestederne: der var
tre, og den fjerde blev glemt — hvilket er præcis sådan, den slap
igennem.

Og rettelsen lavede selv en fejl, som vandringen fangede: da opgavekaldet
holdt op med at fejle, kom en uendelig effekt-løkke frem, som 404'eren
havde holdt låg på. En ubetinget tilskrivning til app.tasks får
projektsidens effekt til at kalde tilbage. 404'eren var låget på en
løkke, ikke bare støj.

Også: -timeout 20m i begge CI-workflows. internal/httpapi tog 664s her og
498s i CI på #95, mod Go's standardgrænse på 600 — og når den krydses, er
beskeden "panic: test timed out after 10m0s" plus et goroutine-dump, som
læser som en deadlock i koden frem for som en suite, der blev for stor.

watchForTrouble udskilt til web/e2e/trouble.js, så udgave-suiten kan bruge
den samme.
