chore(dx): consolidate commands behind make + add editor config

- Make is the canonical interface; pnpm scripts wrap turbo, make wraps pnpm
- CI now calls `make ci-web` / `make ci-desktop` so local == CI
- Add .nvmrc (node 24, matches CI) + engines field
- Add .editorconfig and .vscode (extensions + settings)
- Add `pnpm bootstrap` (deps + Playwright Chromium)
- Add `dev:web` / `dev:desktop` shortcuts
- CONTRIBUTING.md: lead with `make bootstrap`/`make dev-web`,
  link Tauri prereqs, fix wrong `pnpm dev` claim
- CLAUDE.md: command table reflects make-first workflow

 ## Commands
 
+`make` is the canonical interface; it shells out to pnpm scripts which shell out to turborepo. CI calls the same targets — `make help` lists everything.
