fix: remove context propogation as pointer

[GoshaDo]

Pull Request

Description

context.Context is immutable:
The context.Context type and its implementations (e.g., context.Background(), context.WithCancel, context.WithTimeout) are immutable. Each operation that modifies a context (e.g., adding a deadline or attaching values) returns a new context.
This immutability means you can safely pass a context.Context by value without worrying about unintended side effects.

Interface Semantics:
context.Context is an interface, not a struct. When you pass it, you are effectively passing a pointer to the underlying implementation, even though it appears to be passed by value. This makes passing it by pointer unnecessary.
