fix(twister): resolve exemplar package self-imports in lint and editors

The example twists under src/exemplars import @plotday/twister by package
name so their embedded sources show real import paths, but only the build
config could resolve that self-reference — `pnpm lint` (tsc --noEmit) and
editors reported TS2307/TS2339 on those files. Bundler moduleResolution and
the package's own export condition now live in the base tsconfig; the
CommonJS CLI build gets a standalone config since bundler resolution is
incompatible with its output (TS5095/TS5098).

+Fixed: package lint and editor type resolution for the exemplar sources' package self-imports (bundler moduleResolution now applies package-wide; the CommonJS CLI build uses its own standalone config).
