Run Glint's transform through its standalone entry; no TypeScript 5 at runtime - #2

`@glint/ember-tsc/transform/standalone` (typed-ember/glint#1226) analyzes the script parts of a .gts file with ember-estree instead of the TypeScript JavaScript API, so the mapper no longer carries TypeScript 5 at runtime. It stays a devDependency for `lint:types` and the `CompilerOptions` type import in protocol.ts. Script parse errors now take the same path as content-tag errors: the error is reported and no transformed text is returned for the file.

Follows #1. Resolves the "Why does the mapper depend on TypeScript 5?" question from the README: it no longer does.
@glint/ember-tsc1.11.0 ships@glint/ember-tsc/transform/standalone(typed-ember/glint#1226), which analyzes the script parts of a.gtsfile with ember-estree instead of the TypeScript JavaScript API.lib/requests/transform.jsnow uses it, andtypescriptmoves fromdependenciestodevDependencies(still used bylint:typesand theCompilerOptionstype import inprotocol.ts).Script parse errors take the same path content-tag errors already did: the mapper reports the error and returns no transformed text for that file, and TypeScript 7's own parser recovers from there. Same outcome as before for content-tag failures; for the narrower class of errors that swc tolerated but oxc does not, the file used to get a degraded transform and now gets the raw-source fallback.
