Init Workspace Context

1. Auto-detect fields from workspace. Non-obvious: versions.rosetta — read from Rosetta plugin path in current LLM context, e.g. "2.0.43"; versions is for GAIN suite tools only (rosetta, specflow, etc.), not the project
2. Ask user for anything unresolved in a single batch. All fields optional. Prioritize critical fields first. Leave placeholders for skipped fields
3. If gain.json already exists: read it, ask only about gaps and placeholders; never overwrite confirmed values
4. If running as subagent: output gain_json_draft (template with auto-detected values filled in, all other fields left as template placeholders) to orchestrator; instruct orchestrator to ask user to fill in each placeholder field, and leave any unanswered fields exactly as the placeholder in the template
