fix(ui-parser): emit as proper CJS subpackage so ESM named imports work

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
