Missing dependency: pdf-parse not found in application bundle

When attempting to use the parseFile builtin tool on a local PDF file, the tool fails with a module resolution error. It appears the `pdf-parse` package is expected by the internal logic but is missing from the application's resource directory.

## Error Log

`Error: Cannot find package 'pdf-parse' imported from /Applications/Rowboat.app/Contents/Resources/app/.package/dist/main.cjs`

## Steps to Reproduce

1. Attach a .pdf file to the chat.
2. Request a summary or use a tool that triggers parseFile.
3. Observe the error in the tool output.

## Environment

OS: macOS (Darwin)
App Path: /Applications/Rowboat.app

Start by locating the parseFile builtin and the application's dependency or packaging configuration that produces the macOS resource bundle. Reproduce the failure with a local PDF, then verify that the bundled application resolves pdf-parse and successfully completes the PDF summary flow.
