Closes #10

The last piece of the companion (#2). No new features: the gate shows that the pieces work together, keep existing data and leave the offline app as it was.

What the new checks prove (all in tools/test-companero.js, in a real browser)

• Old profile: after opening and caring for the companion, coins, unlocks, palette, character, stats and name are byte for byte the same. A character bought in the core stays the companion's own.
• New profile: goes through the real welcome, wears a rabbit, «medianoche» and a cap, and feeds a fruit. The balance drops exactly what was spent (400 → 5), with no console error.
• Broken data: broken JSON, unknown ids, partial data and a future version each open the page with defaults and the balance untouched, with no console error.
• «Erase everything» in the profile, through the real button and its red confirmation, leaves no chogan.companero.* key.
• No network, no permissions:
  • no companion file uses fetch, XMLHttpRequest, WebSocket, sendBeacon or a remote URL;
  • each module is in the entry's files, so the service worker keeps it offline;
  • the APK still asks only to vibrate.
• Languages:
  • every string in the five languages, none missing or extra;
  • Persian right to left; nothing wider than 390 px;
  • every name fits inside its card (also German at 1280 px);
  • every button has a name for a screen reader.

Documentation

COMPANERO.md (Spanish, for the team) documents:

• the rule: wishes, never needs;
• where coins come from: only from finishing games, via C.stats.record;
• where they go;
• the price of every item, which a test compares against CATALOGO;
• the total of everything permanent: 2,770 coins;
• the stored data, and the decisions.

It is a file of our own, not DECISIONS.md, which belongs to upstream.

One visual fix

In German, «Wasserschwein» broke out of its card. It now breaks at a soft hyphen («Wasser-schwein»), and any long name without one wraps inside its card.

Checks run locally

• node tools/test-companero.js: 197 green (46 new).
• node tools/test.js: 5,610 green.
• ./tools/browser-check.sh: 52 of 52.
• Screenshots at 390 px and 1280 px in the five languages, checked by the owner's agent.
• Merge test with upstream/main: done in Sincronizar con el original 0.20.0 #28/Sync with upstream 0.20.0 (#28) #29. The fork is now level with upstream 0.20.0, so there is nothing left to conflict.

Outside this PR

• The WebCom site (wccr_sitio) leaves the companion out of its game count, in its own PR there.
• The release (v0.20.0-capybara.1) comes after this merges.
