chore: sync VERSION file with release v1.1.261 [skip ci]

- Fix updateApiKey to use JSON.stringify for permissions field
- Add comma-separated string handling in normalizePermissions
- Add frontend parsing for comma-separated permissions format

Fixes issue where selecting multiple permissions (e.g. Claude + OpenAI)
would be saved as "claude,openai" instead of '["claude","openai"]'
