Closes #39

The companion now wants things, and «wishes, never needs» still holds (owner's decision, 2026-11-03).

The rule

• Ganas (eat, play, bathe), from 0 to 3, grow with games finished in the whole app: one level every 3, 4 and 5 games.
  • The count is read from C.stats.get().plays, which the companion never writes.
  • Time away never counts: a year with no games leaves them as they were.
• At 3:
  • the bubble says it in words of wanting («All that playing gave me an appetite!»), and the visit's wish stays as it was;
  • the companion opens eager.
• Tending: any food, play or the soap brings the gana back to 0, with +2 bond when it had reached 2.
• Left alone: nothing happens. No sad face, no lost bond.
• On screen: three small gauges under the bond, each with a name for a screen reader.

Saved data

• Each gana keeps the game count it was last tended at, saved at once.
• Games played before this never count, and a saved care keeps its bond.
• If the core's stats are erased, the counts come down instead of breaking.

Checks run locally

• node tools/test-companero.js: 271 green, twice in a row. New:
  • thresholds 3/4/5 and the cap of 3 (after 3, 5 and 35 games);
  • a year away with no games changes nothing, and a year at the top keeps them at 3;
  • each kind of care tends only its own gana; +2 only from level 2;
  • an old saved care keeps its bond; the core's stats are never written.
• New, in a real browser:
  • gauges at their levels; the bubble speaks the gana at 3 with an eager face;
  • feeding brings it to 0.
• The three new texts in the five languages pass the words-of-need check.
• node tools/test.js: 5,610 green · ./tools/browser-check.sh: 52 of 52.
• Screenshots in Spanish (light) and Persian (dark), checked by the owner's agent.
