[FEATURE] Allow console output throughout a hook's runtime

Problem Statement

I often want to output logs before or during a hook's runtime. Right now, I cannot do that; I can only log outputs at the end.

Proposed Solution

The claude debug seems to show that it parses the output of a log when it appears; it should simply do this on a recurring basis, flushing to the terminal whenever the right input structure is met.

Use Case Example

As an example, I have a hook where I log conversations to a personal database on SessionEnd. Right now, the SessionEnd just looks like it hangs while the writing is occurring. Having some indicator of what is happening would save me a lot of time in using this particular hook.
