feat: add title and description fields to capture grammar

Implement | prefix for titles and // separator for descriptions
across the full stack: parser, schema, API, CLI, and web frontend.

- Parser: line-aware extraction for |title, |title // desc,
  // leading desc, body // inline desc. URL-safe (skips :// lines).
  Modifiers (#tag, @time, ^card) extracted from all segments.
- Schema: ALTER TABLE migration adds title, description columns
- DB: Entity/EntityUpdate structs, all CRUD queries updated
- API: title/description on create/update/response, body validation
  relaxed (title-only entries valid)
- CLI: shows title as scan label when present
- Web: parseInput mirrors Go parser, list shows title, detail pane
  renders title + description with double-click inline editing
- Tests: 10 new cases (grammar, entity, API) — 71 total, all pass
