v2.5

Bug Fixes

• DelayEvent: fixed null pointer dereference when the event name doesn't exist (regression from v2.4)
• Process: fixed potential crash if a callback adds or removes events during iteration — function calls are now deferred until after the event map is fully processed

Changes

• Added singleton.h to the repository (previously expected from the project's source tree)

Docs

• Fixed Instance() / instance() casing inconsistency in the usage examples
• Added GetDelay usage example
