Restructure/frontend editor (#6404)

## Move editor under `frontend/editor/`

Pure restructure: `frontend/` becomes the workspace, `frontend/editor/`
holds
  the PDF editor. 1775 file renames + 40 wiring edits. No logic changes.

  ### Why

`frontend/` is currently the editor — its `src/`, `public/`,
`src-tauri/`,
  config files all sit at the root. Promoting `frontend/` to a
workspace and putting the editor in a sibling folder leaves room for
future
apps to drop in alongside it, sharing one `package.json` /
`node_modules` /
  lint config / Storybook.

  ### What moves

  frontend/
  ├── editor/                ← NEW: everything editor-specific
  │   ├── src/               ← was frontend/src/
  │   ├── public/            ← was frontend/public/
  │   ├── src-tauri/         ← was frontend/src-tauri/
│ ├── index.html, vite.config.ts, vitest.config.ts, playwright.config.ts
  │   ├── tsconfig*.json, tailwind.config.js, postcss.config.js
  │   ├── scripts/
  │   ├── .env, .env.desktop, .env.saas
  │   └── DeveloperGuide.md
├── package.json, package-lock.json, node_modules/ ← workspace install
  ├── eslint.config.mjs, .prettierrc, .prettierignore ← shared tooling
  ├── .gitignore
  └── README.md

  ### Wiring edits (40 files)

  - `.taskfiles/frontend.yml`, `desktop.yml`, `e2e.yml`
  - `build.gradle`, `app/core/build.gradle`
- `eslint.config.mjs`, `frontend/package.json`, `.gitignore`,
`.prettierignore`
  - `docker/frontend/Dockerfile`
  - 8 `.github/workflows/*.yml`, plus `.github/dependabot.yml`,
    `.github/config/.files.yaml`, `.github/labeler-config-srvaroa.yml`
  - `scripts/translations/**`
- Docs: `AGENTS.md`, `CLAUDE.md`, `ADDING_TOOLS.md`,
`DeveloperGuide.md`,
`WINDOWS_SIGNING.md`, `devGuide/HowToAddNewLanguage.md`,
`frontend/README.md`,
    `frontend/editor/DeveloperGuide.md`

Plus 3 renamed + edited: `editor/vite.config.ts` (env path +
node_modules
  walk-up), `editor/scripts/setup-env.mts` (renamed from `.ts` for
`import.meta.url`), `editor/scripts/build-provisioner.mjs` (resolve
src-tauri
  relative to script).

  ### Verification

  | Check | Result |
  |---|---|
  | `task frontend:typecheck:all` (6 variants) | exit 0 |
  | `task frontend:lint` (eslint + dpdm) | exit 0 |
  | `task frontend:format:check` | exit 0 |
  | `task frontend:test` | 657 tests pass, 50 files |
| `task frontend:build:{core,proprietary,saas,desktop,prototypes}` | all
green |
| `task desktop:build` | full Tauri pipeline →
`Stirling-PDF_2.11.0_x64_en-US.msi` |
  | `playwright test --list --project=stubbed` | 172 tests discovered |

`task desktop:build` exercises the heaviest path — Rust + WiX + MSI
bundle
against the moved `editor/src-tauri/`. If anything in the restructure
was
  wrong it wouldn't have built.

  ### Test plan

  - [ ] `frontend-validation.yml` green
  - [ ] `e2e-stubbed.yml` green
  - [ ] `tauri-build.yml` green on at least one platform
  - [ ] `check_toml.yml` runs on a translation-touching PR
