bump: minor type: feature **`ludic.i18n`: keys (phase 26).** A key names what a text is for, and `en.po` says it in English like any other language. A key is a string with a marker byte (`I18N_KEY`, `I18N_PLURAL`), its arguments after byte 31, so the code that makes text never takes `I18nState`: `tr(k)`, `trf(k, a, b, c, d)` and `trn(k, n, a, b, c)` build it, and `L` makes it into text where it is drawn - the language in use, else en.po (read the first time a key is asked for), else the key itself, `[[key]]` in a developer's build (`i18n_loud`). Holes take their arguments in the language's order, a key argument made first; plural keys go by each language's rule. A string with no marker takes the old English path, so a game can move over a file at a time.
