Internal errors during agent deployment (error 10001 and 500)

## Description

Multiple internal errors encountered while attempting to deploy an agent using `blink deploy`.

## Error Details

### First Deployment Attempt
- **Error**: `Failed: get: We encountered an internal error. Please try again. (10001)`
- **Phase**: After build/upload completed, during deployment GET request

### Second Deployment Attempt
- **Error**: `Expected status 201, got 500: { "message": "Internal Server Error" }`
- **Phase**: During file upload (`[8/8] Uploading agent.ts (7.79KB)...`)

## Context

- **Agent**: `matt/vercel-agent`
- **Command**: `blink deploy`
- **Build**: Completed successfully (190ms and 135ms respectively)
- **Upload**: 8 files (4.95MB), 5 environment variables updated
- **Deployment ID**: `35e1d622-f253-42f2-9c44-c61e9857a4c6`

## Impact

User unable to deploy agent due to server-side errors. The deployment appears to build and upload successfully but fails at different stages with internal errors.

## Notes

- Error 10001 appears to be a custom error code in the Blink system
- The 500 Internal Server Error suggests a server-side issue during file upload processing
- Both attempts show the deployment process works up until the final stages
