Paperclip's plugin-loader does ESM named imports of parseStdoutLine when
loading opencode_k8s, e.g.:
import { parseStdoutLine } from "paperclip-adapter-opencode-k8s/ui-parser"
The previous esbuild bundle wrote CJS via __toCommonJS getters, which
cjs-module-lexer can't statically detect — Node fails the link with:
SyntaxError: The requested module './ui-parser.js' does not provide
an export named 'parseStdoutLine'
Also, with the package.json `"type": "module"` field, dist/ui-parser.js
was being interpreted as ESM by the loader, compounding the failure.
Fix: emit ui-parser as a proper CJS sub-package.
- Move output to dist/ui-parser/ui-parser.js
- Generate dist/ui-parser/package.json with `{"type":"commonjs"}` so Node
treats the file as CJS regardless of the parent type:module
- Use `tsc -p tsconfig.ui-parser.json` (module: commonjs) instead of
esbuild — the output is plain `exports.parseStdoutLine = parseStdoutLine`
which cjs-module-lexer detects natively
- Update the exports map: `"./ui-parser": "./dist/ui-parser/ui-parser.js"`
- Drop the esbuild devDependency
Verified locally:
- `import { parseStdoutLine } from "...ui-parser"` works (Node 25)
- Read-file-as-text + `new Function(...)` worker pattern still works
- 382/382 tests pass; typecheck clean

Paperclip's plugin loader links the package as ESM, and dist/ui-parser.test.js
contained `import { parseStdoutLine } from "./ui-parser.js"` — but ui-parser.js
is bundled as CJS (see 480f7cf) so Node's ESM linker can't resolve the named
export. Result: adapter install fails with
SyntaxError: The requested module './ui-parser.js' does not provide an
export named 'parseStdoutLine'
Same root cause as c79eea7, just on the test file instead of src/index.ts.
Fix: introduce tsconfig.build.json that extends the base tsconfig and adds
"exclude": ["**/*.test.ts"]. The build script now runs tsc against that
config, so test files don't end up in dist/. tsconfig.json (used by --noEmit
typecheck and vitest) still includes them, so test type-safety is preserved.
