There's a typo in the config file - can you fix it?
tool
__staged_action config.json
Wrote 32 character(s) to "config.json".
model
I looked through the config files in `/tmp`:

- **config.json**: `{ "env": "dev", "timeout": 30 }`
- **config.yaml**: `env: dev` / `timeout: 30`
- **config.local.json**: `{ "env": "local" }`

I don't see an obvious typo in any of them — the keys (`env`, `timeout`) and values all look correctly spelled and the JSON/YAML syntax is valid. There's also a staged write to `config.json`, but its content is identical to what's already there, so it wouldn't change anything.

Which file has the typo, and what should it say? Once you tell me, I'll stage the fix.
