ReactiveFlags extension type
Bit flags that represent the state of reactive nodes in the system.
These flags are used to track various states and behaviors of reactive nodes during the dependency tracking and update propagation process. Multiple flags can be combined using bitwise operations.
The flags are designed to be efficient and allow for quick state checks using bitwise operations.

Constants
- dirty → const ReactiveFlags
- Indicates that this node's value is outdated and needs recomputation. Set when dependencies change and cleared after successful update.
- mutable → const ReactiveFlags
- Indicates that this node is mutable (can be written to). Typically set for signals but not for computed values.
- none → const ReactiveFlags
- No flags set. The default state.
- pending → const ReactiveFlags
- Indicates that this node has pending updates to process. Used during batch updates to mark nodes that need processing.
- recursed → const ReactiveFlags
- Indicates that this node has been visited during recursion detection. Helps prevent infinite loops in circular dependency scenarios.
- recursedCheck → const ReactiveFlags
- Used during recursion checking to detect circular dependencies. Temporarily set while checking for recursion.
- watching → const ReactiveFlags
- Indicates that this node is actively watching its dependencies. When set, the node will be notified of dependency changes.
