Add coverage tests to github workflow for PRs to main (RooCodeInc#2500)

* add coverage to github workflows

* add changeset

* continue to run on errors

* address comments from ellipsis-dev

* add unit tests, confirm passing

* remove pyproject.toml approach to deps instalL

* use github_output env var

* add verbose mode for debugging

* verbose was not being captured

* std out, not print

* remove 1000 line dump...

* print every line separately to prevent clipping

* build extension before testing

* clean up debugging prints

* break coverage.py into smaller files

* break coverage.py into smaller files

* Relative module names not supported

* rename coverage to coverage_check to avoid naming collision

* rename coverage to coverage_check to avoid naming collision

* debugging missing coverage files

* output error on coverage report

* handling ellipsis-dev comments

* see if we need vscode test deps

* experimenting to try to get it running

* use absolute paths

* put everything in root directory

* address more comments from ellipsis-dev

* import run_command in extraction.py

* fix verbose flag

* use parent parser

* ensure safe command test will allow our commands

* make sure we install before coverage

* update tests to ensure run
