soothe-nano 1.0.7

Fixed

• Import is_rg_available from soothe_deepagents.backends.grep_search (filesystem re-exports were missing in deepagents 0.8.3)
• Omit LangGraph durability kwargs when no checkpointer is present (ephemeral execute twin)

Changed

• Require soothe-deepagents>=0.8.4 for directory-capable glob and grep_search helpers
• Workspace/local glob uses deepagents discovery helpers; drop the local grep_search shim

Added

• Directory glob unit coverage (trailing /, include_dirs)
