* Initial support for module: node12 * Add allowJs and declaration emit enabled tests * Fix typos * cts, mts, cjs, mjs, etc extension support * Fix watch of files whose intepretation changes due to a package.json update * Minor PR feedback * Adjust error message * Initial import/export/self-name support * Accept new error codes * TypesVersions support in export/import map conditions * Fix import suggestion and autoimport default extensions under new resolution modes * Add tests for import maps non-relative name lookup feature * Fix isDeclarationFileName for .d.mts and .d.cts * Preserve new extensions when generating module specifiers * Fix spurious implict any suggestion caused by file ordering bug and optimize import name format detection by relying on parents being set * Fix a bunch of incremental bugs that dont repro under fourslash for some reason * Accept updated baseline * Always include extensions on completions for cjs/mjs style imports * String completion relative import suggestions respect the mode of the import when choosing if they provide extensions * Style feedback * Change diagnostic case
