Add isolated MySQL persistence feature module with HikariCP

[Copilot]

Adds a standalone feature module for MySQL persistence supporting chest limits, sharing, and audit logging. Module is isolated—no modifications to MainPlugin required.

Structure

• DAO interfaces (dao/LimitDao, ShareDao, AuditDao) — contracts for persistence operations
• MySQL implementations (feature/dao/*MySQL) — prepared statements, UUIDs as CHAR(36)
• Services (feature/service/*) — business logic layer with log sanitization
• Example commands — AdminSetLimitCommand, UserShareCommand as CommandExecutor
• Schema (resources/sql/schema.sql) — tables: chest_limits, chest_shares, chest_audit, chest_backups

Integration

// In onEnable()
DatabaseManager dbManager = new DatabaseManager(this);
dbManager.initialize();
// Optional: dbManager.runEmbeddedSchemaIfPresent();

LimitDaoMySQL limitDao = new LimitDaoMySQL(dbManager.getDataSource(), getLogger());
ChestLimitService limitService = new ChestLimitService(limitDao, getConfig());
getCommand("setlimit").setExecutor(new AdminSetLimitCommand(limitService, auditService));

Dependencies (document in pom.xml)

<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
    <version>4.0.3</version>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.28</version>
</dependency>

Notes

• runEmbeddedSchemaIfPresent() is explicit opt-in, not automatic
• Schema splits on ; with SQL comment filtering—complex schemas should be run manually
• Full integration guide in README-feature.md

Original prompt

Adicionar um módulo feature isolado para persistência MySQL no plugin MyChest. O módulo deve ser colocado sob mychest/src/main/java/com/github/yannicklampers/mychest/feature e deve incluir DAOs MySQL, serviços e comandos de exemplo, assim como arquivos de recurso (config.yml e sql/schema.sql). Também incluir interfaces DAO em mychest/src/main/java/com/github/yannicklampers/mychest/dao para compatibilidade.

Arquivos a adicionar (conteúdo já especificado):

• mychest/src/main/java/com/github/yannicklampers/mychest/dao/LimitDao.java
• mychest/src/main/java/com/github/yannicklampers/mychest/dao/ShareDao.java
• mychest/src/main/java/com/github/yannicklampers/mychest/dao/AuditDao.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/database/DatabaseManager.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/dao/LimitDaoMySQL.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/dao/ShareDaoMySQL.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/dao/AuditDaoMySQL.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/service/ChestLimitService.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/service/ShareService.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/service/AuditLoggerService.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/commands/AdminSetLimitCommand.java
• mychest/src/main/java/com/github/yannicklampers/mychest/feature/commands/UserShareCommand.java
• mychest/src/main/resources/config.yml
• mychest/src/main/resources/sql/schema.sql
• mychest/README-feature.md

Requisitos e comportamento esperado:

1. DatabaseManager deve inicializar HikariCP a partir de config.yml e expor DataSource. Deve ter método opcional runEmbeddedSchemaIfPresent() que executa resources/sql/schema.sql (dividindo por ';') caso o administrador permita execução automática.
2. DAOs MySQL devem usar DataSource e consultas preparadas. Use UUIDs como strings (CHAR(36)).
3. Serviços encapsulam lógica e delegam para DAOs.
4. Comandos de exemplo: AdminSetLimitCommand e UserShareCommand como CommandExecutor. Eles devem escrever logs de auditoria via AuditLoggerService.
5. Incluir config.yml com parâmetros mysql (host, port, database, user, password, poolSize, useSSL) e settings.default_slots e settings.audit_retention_days.
6. Incluir schema SQL para criar tabelas chest_limits, chest_shares, chest_audit, chest_backups (JSON).
7. Não modificar MainPlugin diretamente — o módulo é isolado. No README-feature.md incluir instruções de integração (instanciar DatabaseManager, criar DAOs e serviços, registrar comandos e opcionalmente executar schema no onEnable).
8. Atualizar pom.xml não será feito automaticamente — documentar dependências necessárias (HikariCP e mysql-connector-java) no README-feature.md.

Critérios de aceitação:

• Todos os arquivos listados são adicionados ao branch feature/mysql-persistence com código compilável (sem dependências externas além do plugin padrão e as dependências mencionadas).
• README-feature.md descreve claramente como integrar o módulo ao plugin existente e como executar o schema.
• DatabaseManager.runEmbeddedSchemaIfPresent não executa automaticamente por padrão — deve ser chamado explicitamente no onEnable() se desejado.

Commit message sugerida: "feat: add mysql feature module (limits, shares, audit) with HikariCP"

Por favor, crie um PR da branch feature/mysql-persistence para master contendo esses arquivos e use o título do PR igual ao problem_title. Descreva no corpo do PR um resumo das mudanças, instruções rápidas de integração e observações sobre execução do schema e dependências.
