Lifesteal Plugin

🧠 Architecture & Design

1. Centralized Utility APIs – MessageUtils, ColorUtils, ItemBuilder provide DRY, reusable patterns.

2. Singleton-safe plugin access – consistent use of getInstance() for global plugin reference.

3. Separation of concerns – clearly segmented managers (HeartManager, BanManager, etc.) avoid bloated main class.

4. Graceful failover & shutdown – plugin disables on fatal error; database and recipes properly closed.

5. Dynamic command delegation – uses executor-permission binding; fallback warnings for missing entries.

⚙️ Code Quality & Safety

1. Null safety added – guards against null messages, lists, strings, ItemMeta, etc.

2. Cloning of mutable objects – avoids returning internal ItemStack references directly.

3. Input validation – amount clamped (1–64), tier limited (1–5), keys checked.

4. Regex matching via Matcher.appendReplacement() – safe and efficient HEX color parsing.

5. Safe config fallback – missing lang keys gracefully return default with warning.

📈 Performance Improvements

1. Efficient string coloring – reused helper for batch lore coloring reduces overhead.

2. Deferred meta setting – avoids redundant operations on ItemMeta.

3. Command tab completer registered conditionally – avoids NPE if command is missing.

📜 Documentation & Readability

1. Full JavaDocs added – method-level docs explain parameters, return values, and side effects.

2. Consistent naming and formatting – fluent, descriptive method and variable names.

3. Simplified logging interface – log(String) method wraps colored console output.

🚨 Error Handling & Logging

1. Fallback logs for lang keys – warns when translation keys are missing.

2. Structured exception logging – prints full stack trace on startup failure.

3. Invalid hex codes skipped silently – prevents plugin crash from user config errors.

🧩 Extensibility Support

1. Lore overloads and builder extensibility – builder pattern allows for chaining, expansion (e.g., enchantments).

2. Formatted string retrieval in LangManager – supports runtime placeholders with String.format(...).
