Where should the reviewer start?
Following the logical flow starting from lib/analyzer/static-analyzer.ts will be easier to follow.

How should this be manually tested?
Using the Docker registry agent(DRA) (https://github.com/snyk/docker-registry-agent) update the installed Snyk docker plugin version (in the package.json) to be based on the current branch:
"snyk-docker-plugin": "github:snyk/snyk-docker-plugin#collect_application_files".
Run npm install.
Run the DRA locally and from a different terminal execute the following command:

curl --location 'http://localhost:17500/scan' \
--header 'snyk-source-credentials: <<CREDENTIALS_FOR_CR>>' \
--header 'Content-Type: application/json' \
--data '{
    "target": {
        "name": "<<IMAGE_ON_CR>>"
    },
    "options": {
        "appScan": true,
        "collectApplicationFiles": true
    },
    "callbacks": {
        "resultUrl": "<<RESULT_URL>>",                                   
        "doneUrl": "<<DONE_URL>>",
        "token": "00000000-0000-0000-0000-000000000000"
    }   
}'

The expected output of the given RESULT_URL endpoint should contain the fact type "applicationFiles" as part of the data.
The image should be running Java code.
