feat: tell shoppers what a released Pokémon keeps

[LuceteYang]

Why

I bought an egg expecting to lose the Pokémon I was raising — and specifically expecting it to disappear from my Pokédex. Reading the code afterwards, I was wrong on both counts that matter.

The card says only "Send off your current Pokémon and start fresh with a new egg." Nothing follows it, so "send off" reads as "lose it", and the shiny warning sitting right next to it reinforces that something irreversible is happening.

What actually happens:

• buyEgg() appends releasedDexEntry(from:) before clearing the active Pokémon, so the species stays in the Pokédex. FreshEggTests.testReleasedSpeciesStaysInTheDex locks this in.
• chooseBase() halves the hatch weight of any base whose line you have already completed. That check reads collectedFinals, which only graduate() fills — releasing leaves it untouched, so a released Pokémon keeps its full weight and can hatch again at the same odds.

The one thing you do give up is the growth progress. The shop says none of this, so the card reads scarier than the feature is.

And in Korean, where the description fits on one line so the note costs two:

_{Rendered the same way as scripts/gen-settings-screenshots.py does its assets — the popover cannot be opened from a script, so the card is drawn in HTML with the colours and metrics sampled from assets/screenshot-shop.png / -ko.png.}

What changes

Adds eggReleaseNote right under eggDescription:

A released Pokémon stays in your Pokédex and can hatch again at the same odds — only the growth progress is lost.

It goes in the description column rather than the price row, which belongs to the price, the button and eggShopLockedHint. Rendered only while there is a Pokémon to release. Translated for all seven languages.

Re-incubation is deliberately left out — eggDescription already says the new egg starts from scratch, and repeating it pushed the German string to three lines.

Testing

swift build and swift test (1048 tests) pass.
