One-time migration of legacy state files into ~/.deepagents/.state/.
Earlier versions wrote internal state directly under ~/.deepagents/,
mixing it with user-facing agent directories (so e.g. mcp-tokens/
showed up in deepagents agents list). State now lives in a dedicated
.state/ subdirectory; this module moves any legacy files into place
on startup.
The migration is best-effort and idempotent: it skips entries whose destination already exists, logs and continues on per-entry failures, and never blocks startup on I/O errors.
Directory for user-level Deep Agents configuration (~/.deepagents).
Directory for app-managed internal state (~/.deepagents/.state).
Holds files the app writes for its own bookkeeping — OAuth tokens, the
sessions database, version-check caches, input history. Kept separate from
top-level user-facing config and agent directories so listing/iterating
~/.deepagents doesn't conflate state with agents.
Marker filename under ~/.deepagents/.state after onboarding has completed.
