Description

Previous refactoring (most recently 6ce7679) worked towards making nearly every get/set occur from the top level. Refactor so that helper procs always get/set from the top level, so that we no longer write getChalkScope() when getting/setting or similar.

Before this PR, there was a lot of getChalkScope() noise:

$ git log --oneline -1
6470eaf4 (HEAD -> main, crashappsec/main) fix: using none log level for chalk exec in interactive shell (#394)
$ git grep 'getChalkScope()' -- '*.nim' | wc -l
265

With this PR, the remaining getChalkScope() outside run_management.nim are mostly nil comparisons:

$ git log --oneline -1
fa1f99b (HEAD -> ee7/reduce-getChalkScope, crashappsec/ee7/reduce-getChalkScope) Merge branch 'main' into ee7/reduce-getChalkScope
$ git grep --ignore-case 'getChalkScope' -- '*.nim' | wc -l
14
$ git grep --break --heading --ignore-case 'getChalkScope' -- '*.nim'
