Question1:

namespace ts{
        export const enum SyntaxKind {
        Unknown,
        EndOfFileToken,
        SingleLineCommentTrivia,
        MultiLineCommentTrivia,
        NewLineTrivia,
        }
}

var q = (ts as any).SyntaxKind;

const enum SyntaxKind {
    Unknown,
    EndOfFileToken,
    SingleLineCommentTrivia,
    MultiLineCommentTrivia,
    NewLineTrivia,
}

// How to get SyntaxKind like under namespace?

For now I generate a new file and copy everything in need expect the "const" keyword.

Some aim:

1. remove all "ts" namespace, keep others for temp. (ts.XX keeps too)
2. NOT change indent, so review could be possible.
3. use script to do heavy work, but manually check all again and fix error.

Some sequelae caused by this branch:

1. some variable are renamed, they are usually added "NameSpaceLocal" suffix.
2. indent in some test files and their baseline are changed.

How to deal with namespace:

1. for those which only have one (in another word, not merged)
   1. if it is used in multi projects, keep namespace and export it.
   2. if it is only used in one project, just delete the namespace and remove the namespace name in used place
2. for those which have multi parts (merged)
   How to do with it?

why importTracker.ts is not in findAllReference.ts?

@ShuiRuTian FYI, #35561 already does this and is (re)generated by script. We're mostly just blocked on an API Extractor feature so we can preserve the same file layout in our API as today.

whoops, glad to know that!
