Update extension to v0.1.2:
Triple-fix for the env-var loading issue that broke v0.1.0 and v0.1.1:
- Hardcoded fallback for the API URL — even if the env-var pipeline fails entirely, the popup now boots cleanly
- Turbo's env passthrough fixed so future PLASMO_PUBLIC_* vars aren't silently dropped
- CI now writes apps/extension/.env.production from a GitHub secret before building (Plasmo's preferred env-loading path)
Effect for users: popup actually opens this time. v0.1.0 and v0.1.1 were dead-on-arrival.
