Localization (i18n)

The debugger's user-facing messages (runtime errors and the adapter's replies to the editor) live in one place, shared by the plugin and the adapter:

Where	What
crates/protocol/src/messages/mod.rs	Locale, MsgKey (the keys) and the routing (msg/format)
crates/protocol/src/messages/langs/<code>.rs	one match table per language: get(MsgKey) -> &'static str

The texts are templates with positional {} markers, filled in by messages::format(locale, key, &[args]). The language comes from the editor (the locale argument of initialize, in the adapter; the PAWNPRO_DBG_LOCALE env var, in the plugin) and is resolved by prefix (Locale::from_tag); an unknown one falls back to English.

There are 11 message keys (5 runtime errors + 6 from the adapter). Each language's match on MsgKey is exhaustive — a missing key does not compile. That is why a language marked ✅ necessarily covers all 11.

Legend: ✅ complete · 🟡 partial · ⬜ missing.

Coverage goal: at least 50 languages. The order prioritizes historical relevance in the SA-MP / open.mp community. Today there are 5 implemented.

Adding a language

1. Create crates/protocol/src/messages/langs/<code>.rs with pub fn get(key: MsgKey) -> &'static str covering every MsgKey (keeping the {} markers in the same logical position).
2. Register the module in langs/mod.rs (pub mod <code>;).
3. Add the variant to the Locale enum, to Locale::from_tag (by prefix) and to the match in messages::msg.
4. Mark it ✅ in this table.
