fix: declare codemirror-json5 module typings and clarify release build

Add ambient declarations for codemirror-json5 exports (language, linter,
defaults) so TypeScript resolves those imports.

Use `bun run build` in the release npm script so the package build script
runs explicitly rather than relying on Bun’s build shorthand.
