Remove wildcard exports

[vsumner]

Description

Follow up to: #2209

Update all package exports to remove "./*". From node documentation:

As a last resort, package encapsulation can be disabled entirely by creating an export for the root of the package "./": "./". This exposes every file in the package at the cost of disabling the encapsulation and potential tooling benefits this provides. As the ES Module loader in Node.js enforces the use of the full specifier path, exporting the root rather than being explicit about entry is less expressive than either of the prior examples. Not only is encapsulation lost but module consumers are unable to import feature from 'my-mod/feature' as they need to provide the full path import feature from 'my-mod/feature/index.js.
