fix: pass all go tests in lang/ (#60)

* docs: fix typo, clearify function names

* feat(tests): group tests by language

* tests: add testutils, fix all tests in ./lang/lsp

* lang/lsp/utils_test.go: no change
* lang/lsp/client_test.go: test basic LSP clients
* lang/lsp/lsp_test.go: removed because `TestDocumentSymbol_MarshalJSON` is covered in client_test.go

* tests: pass lang/collect tests, testutils in lsp

Pending lang/patch tests because localsession.json contains paths on
Yi's machine. Freshly generating localsession.json fixes the issue, but
let's confirm.

* tests: pass lang/uniast tests

* fix: make testutils work for any subpackage

* typo

* tests: update status for go tests

* tests: update status for rust tests, improve rust.utils.hasIdent

* tests(parse): check node.Content/Offset consistency

* tests: fix golang/writer tests

* tests: add go test CI
