live: add debug info to join handler writes

[kevboh]

Summary by CodeRabbit

Bug Fix:

• Enhanced error handling in joinHandler's Write method: Now, in case of a write failure, the system will return a more detailed error message. This includes the attempted write and a stack trace, which will help in diagnosing and resolving issues more effectively. This change is not directly visible to end-users but will improve overall system reliability and maintainability.

• 4-8: The runtime/debug package has been added to the import statements. This package provides functions that expose information about the runtime and the goroutine state, which can be useful for debugging.

• 23-25: The Write method of the joinHandler struct has been modified. Previously, it returned an error message stating that joinHandler.Write does not accept writes. Now, it also includes the attempted write and a stack trace in the error message. This change will provide more context when debugging issues related to write operations in the joinHandler.
