Local environment bridge

Fill another project’s .env from Arka’s local configuration.

arka env-bridge /path/to/project
arka env-bridge /path/to/project --allow OPENAI_API_BASE,OLLAMA_HOST --apply

The bridge is deterministic and local-only; it does not send values to an LLM. It redacts values in previews, never overwrites existing keys, and requires --apply before writing. Prefer --allow to limit the variables copied.
