Add and Replace SLASH and ROOT constants

[chahmedejaz]

Overview

• This PR adds the SLASH and ROOT constants and replaces them throughout the agent.
• I created the ROOT (/) constant because I felt that we are using it in the path's context in many places as well
• I thought it would be handy to separate it out into a new constant.

I assigned the SLASH to SEGMENT_SEPARATOR because I felt, the SEGMENT_SEPARATOR is the best name for the context for SLASH here. Please let me know if you think otherwise.

Having one constant reference another gives us the benefit of using a more context-specific name while still minimizing resources and not* maintaining two copies of the same frozen string. I really like your approach here, @chahmedejaz.
