consistent formatting rules

Maintain consistent formatting throughout the codebase to improve readability and maintainability. This includes standardizing function declaration spacing, comment styles, pointer/reference formatting, and type naming conventions.

Key formatting rules to follow:

1. Function declarations: Use consistent spacing around braces and parameters ```cpp // Preferred - consistent spacing const NATSConnectionPtr & getConnection() { return connection; } const std::vector & getSubjects() const { return subjects; }

// Avoid - inconsistent spacing
const NATSConnectionPtr & getConnection(){return connection;} const String & getQueueName() const{return queue_name;}

2. **Comments**: Use triple slashes (///) for single-line comments instead of double slashes (//)
```cpp
/// Implements `instrumentation` system table, which allows you to get information about functions instrumented by XRay.
// Avoid: // Get a vector of indices.

1. Pointer and reference formatting: Add spaces around * and & operators ```cpp // Preferred std::vector getIndices(const GinFilter * filter, const PostingsCacheForStore * cache_store) const;

// Avoid std::vector getIndices(const GinFilter *filter, const PostingsCacheForStore *cache_store) const; ```

1. Type naming: Follow project conventions (e.g., UInt32 instead of uint32_t in ClickHouse codebase)

Consistent formatting reduces cognitive load during code reviews and makes the codebase more professional and maintainable.
