## Problem
The command `curl URL | bash` isn't interactive because curl's output
consumes bash's stdin, preventing user prompts from working.
## Solution
Use bash process substitution instead: `bash <(curl URL)`
This keeps stdin available for the script while downloading from curl.
## Changes
- Added INTERACTIVE_CURL.md - Complete guide to interactive execution
- Added NON_INTERACTIVE_MODE.md - Guide to automation/CI usage
- Updated README.md to recommend `bash <(curl ...)` format
- Documented OpenRouter URL alias pattern
## Recommended Usage
Interactive (best UX):
bash <(curl -fsSL https://openrouter.ai/lab/spawn/sprite/claude.sh)
Non-interactive (CI/CD):
SPRITE_NAME=dev-mk1 curl URL | bash
## Why Process Substitution?
- Stdin available for prompts ✅
- Works like normal bash script ✅
- No /dev/tty workarounds needed ✅
- Better user experience ✅
Both methods are supported for maximum compatibility.
