feat(notes): fundamentet — Markdown, søgning og links begge veje

Første etape af noter. Tabel, CRUD, fuldtekstsøgning og de links, en note bærer. Markdown i en kolonne, ikke rich text og ikke et format af vores eget. Eksport var et krav, før der var skrevet en linje, og er den gemte form den eksporterede form, er der ingen konvertering tilbage at tabe noget i — noten kan læses af enhver anden editor den dag programmet ikke findes. Et #tag i en note er DET SAMME tag som i en opgave. Ikke en anden slags, der ligner. Det er hele svaret på "tag en note og se den i projektet": referencen er den samme, så der ikke opstår to systemer, brugeren selv skal holde i sync. Links gemmes som rækker, udledt af teksten ved hver gemning. Teksten er stadig sandheden; tabellen er et indeks over den. Uden det ville "hvad peger på denne opgave" betyde en gennemsøgning af al prosa, og den rude ville være for langsom til at lade stå åben. De rives ned og bygges op frem for at blive sammenlignet: en sammenligning er en anden beskrivelse af samme kendsgerning, og den kan komme til at være uenig med teksten. Noter ligger under projekter og arver deling, roller, papirkurv og historik. En mappestruktur ved siden af ville være ét hierarki for meget. MatchExpr fik navngivne kolonner. Den var skrevet til opgavernes og gav "no such column" mod noternes — hvilket i det mindste er højlydt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

+-- Notes.
+--
+-- Markdown in a column, not rich text and not a format of our own. Export was a
+-- requirement before a line was written, and if the stored form *is* the exported
+-- form there is no conversion left to lose anything in — a note stays readable by
+-- any editor on the day this program is gone. It is also what makes full-text
+-- search and anything an AI does over notes cheap: both read text.
+--
+-- Under a project rather than in a folder tree of its own. Projects, groups and
+-- labels already exist and are already shared, already have roles, already have a
+-- trash. A second hierarchy to file things in is one too many, and a note that
+-- belongs to a project inherits every one of those answers instead of needing its
+-- own. A note with no project is loose, the way a task in the inbox is.
+--
+-- `deleted_at` and `created_by` follow tasks exactly, including SET NULL: an
+-- account can be removed without taking somebody else's notes with it.
