Merge pull request #5 from feat/void-protection

Wires the new ADDITIONAL_CONTEXT_URL feature on the central webhook service
(see gitea_admin/pragent e8ebc54) — fetches a static maintainer-curated brief
from the Nexus raw-hosted repo at review time. The doc distils the house
rules so the agent doesn't have to re-derive them from the diff each PR:

* chat messages are immutable after send (counts baked into buttons freeze)
* translatable components + singular-form rule for pt-BR sentences
* Geyser/Bedrock can't click — every click has a typed fallback
* vanilla stats only — <world>/players/stats/<uuid>.json, NOT <world>/stats
* reactions keep counting late (reacao-validade-minutos)
* Floodgate is optional runtime, never compile-time

Plus the canonical focus/instructions/languages config: java, balanced style,
claude-sonnet-5 cost target, JDK 25 build note.

Avoid main-thread I/O; defer expensive scans (chunk loading, spiral search) to scheduled tasks or async paths. Flag mutable shared state across listener invocations. Hard constraints: chat messages are immutable after send (counts baked into buttons freeze at send time); names go out as translatable components so the singular-form rule applies (number never agrees with the noun); Geyser/Bedrock cannot click and cannot show emoji (every click has a typed fallback); vanilla statistics are the only data source (offline path is <world>/players/stats/<uuid>.json, NOT <world>/stats); reactions keep counting late (reacao-validade-minutos); Floodgate is optional runtime dep. Flag: real bugs, missing persistence of new settings, comando/permission not in plugin.yml, breaking Bedrock equivalent invariant, removing the frozen-at-send assumption, violating singular-form rule, missing Stats.resolve() on renames."

+# Spec: Proteção de Itens no Vácuo (Void Protection)
+
+## 1. Problema e Motivação
+Quando um jogador morre no vácuo (caindo no The End, Nether ou Overworld profundo), todos os itens e armaduras caem abaixo de Y = -64 e são excluídos pelo motor do Minecraft, impossibilitando qualquer recuperação legítima e gerando frustração.
+
+## 2. Solução
+Implementar o módulo `salvavoid` no plugin Canalhandia:
+1. **Detecção:** Identifica mortes por vácuo (`DamageCause.VOID` ou coordenada Y abaixo da altura mínima do mundo).
+2. **Busca de Terreno Seguro:** Procura o bloco sólido mais próximo da posição horizontal onde o jogador caiu (raio configurável, padrão 32 blocos).
+3. **Opção A (Baú de Resgate):** Se encontrar terreno seguro:
+   - Cria um baú (ou baú duplo se necessário) sobre o bloco seguro.
+   - Guarda todos os itens e armaduras do jogador dentro do baú.
+   - Limpa os drops do evento de morte (para não cair no vácuo).
+   - Informa ao jogador a localização exata (coordenadas X, Y, Z) do baú no chat.
+4. **Opção B (Preservação Direta no Inventário):** Se NÃO houver nenhum bloco seguro por perto (ex: caiu no meio do vácuo infinito do End):
+   - Preserva o inventário e nível de XP do jogador (`keepInventory = true`, `keepLevel = true`).
+   - Limpa os drops do evento de morte.
+   - Envia mensagem confortando o jogador e avisando que os itens foram mantidos no inventário.
+
+## 3. Critérios de Aceitação
+- Módulo integrado ao `/canalhandia modulo salvavoid <on|off>`.
+- Configurações em `Settings.java`: `voidProtectionEnabled`, `voidProtectionRadius`, `voidProtectionKeepXp`.
+- Testes unitários cobrindo detecção de morte no vácuo, cálculo de busca e empacotamento de inventário.
