A tiny on-chain virtual pet. Hatch one, then keep it alive by feeding, playing,
and letting it sleep — hunger, happiness, and energy all decay with block
height, so neglect (or just forgetting to check in) eventually kills it.
Hatching a new pet after a death keeps your lifetime feed/play/death counts,
so the leaderboard rewards long-term care rather than a single lucky run.

Realm: `gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/tamagotchi`

## Example calls

```
maketx call ... -func Hatch -args "Fluffy"     # start a pet
maketx call ... -func Feed                     # -30 hunger, +5 energy
maketx call ... -func Play                     # +20 happiness, -10 energy, +5 hunger
maketx call ... -func Sleep                    # +40 energy, +5 hunger
```

`Render("")` lists every pet ever hatched with alive/dead status and lifetime
stats. `Render("<owner-address>")` shows one pet's detail card.

## Toolchain status

`gno test .` passes (10/10 tests) against `~/p/gh/gnolang/gno` as `GNOROOT`.
Uses only `chain/runtime`, `sort`, `strconv`, and the kept `gno.land/p/nt/avl/v0`
/ `gno.land/p/nt/testutils/v0` packages per the sapphire stdlib reference. Panic
paths are tested through non-crossing helper functions (`hatch`, `feed`,
`play`, `sleep`) rather than through the exported `cur realm` entry points,
since panics raised inside a realm-crossing call aren't `recover()`-able from
the caller on this toolchain version.
