monorepo eslint misconfiguration

[wonrax]

Due to misconfiguration, eslint does not have any effect on the files. Moreover, eslint is throwing error because it couldn't find any files to operate on. This PR https://github.com/orochi-network/zkDatabase/pull/291 temporarily disables the lint so that CI can pass.

We need to fix the eslint configuration by properly using the new flat config format, which must support monorepo and the ability to support per package customization.
