Reorganize documentation and unify the AI assistant rules

Documentation:
- Add docs/README.md, the documentation index that AGENTS.md pointed to as the
  first file to read but which did not exist.
- One home per piece of information: the feature list stays in ROADMAP.md,
  CHANGELOG.md records only when something shipped, TODO.md only ongoing work.
  Reconcile the entries that had drifted (CSI was both done and pending;
  pagelle, badge social and serie were missing from the roadmap).
- Rewrite DATABASE.md as tables: add giocatori_squadra (already created by a
  migration) and profili_giocatore (planned in DD-016), fix the wrong heading
  levels, drop the duplicated roadmap.
- DESIGN_DECISIONS.md: move the index to the top and sort it, extract the
  template into _template-dd.md.
- ARCHITECTURE.md becomes the technical reference; CLAUDE.md no longer
  duplicates it.
- Add docs/EFFICIENZA_CLOUD.md with the rules previously kept in mem/,
  separating what the code enforces from the goals not yet implemented.
- Fix statements the code contradicted: mutations use setQueryData rather than
  invalidateQueries, and scout_sessioni and giocatori_squadra are not read by
  the code yet.
- Track the v1.0 modules with no spec in docs/modules/ from TODO.md.

AI assistants:
- AGENTS.md is the single source of the rules, now including the technical
  constraints only Claude Code knew about (generated files, Vite plugins, data
  access) and an end-of-work checklist that applies to every assistant.
- CLAUDE.md and .cursor/rules/crapp.mdc point to AGENTS.md instead of
  restating it.
- Remove the five .cursor/*.md files, which Cursor never loaded.
