Deleted the src/backend-core-0 package and moved its validation helpers directly into src/backend/src/validation.js. Updated references in CoreModule.js and helpers.js to use the new local validation module. Adjusted ESLint configs to remove backend-core-0 references.
This commit adds verification for statically identifiable definite
errors. Sometimes global variables used will be falsely reported as
undefined variables in which case the new file
`mandatory.eslint.config.js` should be updated to include these
definitions in the narrowest scope possible that has these definitions
The styleguide for Puter's backend expects spaces after top-level not
operators inside conditions. This commit adds an AI-generated eslint
plugin and, since it conflicts with the existing space-unary-ops plugin
from stylistic, also adds a wrapped version of space-unary-ops that
ignores top-level not operators so that this plugin will work as
expected.
