fix(index): drop ESM re-export of parseStdoutLine from CJS ui-parser

dist/ui-parser.js is bundled as CJS (480f7cf, so the sandboxed UI worker
can load it via new Function), but src/index.ts re-exported a named
binding from it as ESM:

    export { parseStdoutLine } from "./ui-parser.js";

Since the package is "type": "module", Node's ESM loader resolves the
import as ESM and can't find named exports on a CJS module bundle —
linking fails at adapter-load time:

    SyntaxError: The requested module './ui-parser.js' does not provide
    an export named 'parseStdoutLine'

The adapter then gets dropped on every Paperclip pod restart with only
claude_k8s surviving. Nothing in the runtime imports parseStdoutLine
from the package root — the plugin-loader serves ui-parser.js to the UI
worker by reading it as a string (server/src/adapters/plugin-loader.ts),
and tests import the TS source directly. Removing the re-export.
