feat: rename form-copilot/ → copilot/ + brand → SimplePDF Copilot (#31)

## Background

Renames the standalone demo from "Form Copilot" to "SimplePDF Copilot"
and reorganises the folder. Stacked with the parent SimplePDF repo PR
SimplePDF/simple-pdf#196.

## Changes

- `git mv form-copilot/ copilot/` (history preserved).
- `package.json` `name`, `.cta.json` `projectName`,
`.do/deploy.template.yaml` `name` + `source_dir` updated to `copilot`.
- README: brand "Form Copilot" → "SimplePDF Copilot" everywhere; live
URL `form-copilot.simplepdf.com` → `copilot.simplepdf.com`; deploy
folder ref `/form-copilot` → `/copilot`; default
`VITE_SIMPLEPDF_COMPANY_IDENTIFIER` documentation flipped to
`spdf-copilot`.
- `skills/fork-and-go/SKILL.md`: same brand + path + placeholder
identifier sweep.
- Source-tag query param `?s=form-copilot` → `?s=copilot` across info /
layout / download modals.
- GitHub source-code chip URL `tree/main/form-copilot` →
`tree/main/copilot`.
- ASCII architecture diagrams in the info modal: brand box width
preserved (`│ Form Copilot │` → `│ Copilot │`, both 17 chars; header
`┌── Form Copilot demo ──┐` → `┌── SimplePDF Copilot ──┐`, both 25
chars).
- `mode.ts` `COPILOT_DEMO_IDENTIFIER` `'copilot'` → `'spdf-copilot'`
(matches the renamed SimplePDF account that hosts the iframe editor).
- `en.json`: every "Form Copilot" → "SimplePDF Copilot" (one-shot
replace_all).
- 22 non-EN locales (`ar, cs, da, de, el, es, et, fi, fr, he, hi, it,
nl, no, pl, pt, ro, sv, tr, uk, vi, zh`) translated by the translator
agent. Inflected forms preserved (et `Form Copiloti`, fi `-in/-ia/-iin`,
pl instrumental `-em`, tr apostrophe-suffixed). Brand kept Latin in
every locale.

## Notes

Kept intentionally for backward compatibility (commented):
- `WELCOME_DISMISSED_COOKIE = 'form-copilot-welcome-dismissed'` —
renaming would force returning visitors back through the welcome flow.
- `DB_NAME = 'form-copilot-vault'` — renaming would orphan stored BYOK
credentials.
- CDN paths under `/simple-pdf/assets/form-copilot/*` —
operator-controlled assets, not yet moved.

`copilot/.env.example` is sandboxed in this session (not editable via
tooling) — operator must change
`VITE_SIMPLEPDF_COMPANY_IDENTIFIER=form-copilot` to
`VITE_SIMPLEPDF_COMPANY_IDENTIFIER=spdf-copilot`.

Operator follow-ups (post-merge):
- DNS / DO App Platform: deploy `form-copilot.simplepdf.com` →
`copilot.simplepdf.com`.
- SimplePDF account: rename `copilot` → `spdf-copilot` (the
iframe-editor host).
- CDN: move `/simple-pdf/assets/form-copilot/*` and
`/simple-pdf/assets/meta/form-copilot-*.png` under a `copilot/` prefix.

## Test plan

- [x] `cd copilot && npx tsc --noEmit` clean
- [x] `cd copilot && npx vitest run` 53/53
- [x] `cd copilot && npx biome check src/` clean (2 pre-existing
warnings, unchanged)
- [x] All 23 locale JSON files parse

 ## Programmatic Page Control
 
-Currently, page manipulation (add/remove/re-arrange/rotate) is only available through the UI. There are no programmatic APIs for these operations. If you need this feature, [file an issue on the repository](https://github.com/SimplePDF/simplepdf-embed/issues).
+Page manipulation is available programmatically through the iframe `postMessage` API. Each event takes 1-indexed visible-page positions (matching the `current_page` that `PAGE_FOCUSED` reports).
 
 **Available programmatic actions:**
 
-| Action                 | Description                                                                                                |
