feat(sagi): custom pets — Codex pet bundles, images, featured downloads

The mascot can wear a pet. Right-click it for Hide pet, Size (48-250
px), Choose pet (Sagi, featured, your own - deletable), Upload your
own..., Import .codex-pet bundle..., Find more on codex-pets.net and
Pet settings.... The worn pet and its size are viewer prefs
(agenthub.pet, agenthub.pet.size); the pets live on the server under
<data dir>/pets/<id>/ (server/lib/pets.js, /api/pets).

A Codex pet is the .codex-pet.zip format: pet.json + a 1536x1872
spritesheet.webp, 8x9 frames of 192x208, one row per state.
PetSprite.tsx plays the row of the mascot's mood; an uploaded image
bobs. Only the two bundle files are read, sizes are checked from the
zip directory before inflating, the sheet's WebP header must match,
uploads are raster only (no SVG), ids are made by the server, every
write is same-origin.

The four featured pets (Goku, Bac Ho, Border Collie, 11) are
codex-pets.net uploads with no redistribution licence, so none is
bundled: a pick downloads it from codex-pets.net by a fixed id.

/**
* @file PetMenu.tsx
* @description The mascot's right-click menu: hide it, size it, choose the
* pet it wears — Sagi, a featured pet (downloaded from codex-pets.net into
* this install on the first pick, `POST /api/pets/featured/:id`), or one of
* your own (deletable) — upload an image or import a `.codex-pet.zip`, browse
* codex-pets.net for more, and open the Sagi settings. The choice and the size
* are viewer preferences (`prefs.ts`); the pets themselves live on the server
* (`server/lib/pets.js`).
