v1.25.7 - Pack skips the login/onboarding flow

Fixes enigma <pack> still asking to log in even with a valid seeded token.

Root cause: the isolated context's .claude.json lacked hasCompletedOnboarding, so Claude Code ran its onboarding flow (which asks you to log in) and ignored the perfectly valid token. Seeding now mirrors the seeding account's .claude.json state (onboarding flags, identity, preferences - project history dropped, the pack's own MCP servers kept) into the context, so the agent treats it as the same already-signed-in install and goes straight to chat. It runs even when only the token was kept from a previous launch, so an existing context is repaired on the next run. Only the pack context is written - never your account.
