Summary

Netclaw v0.15.1 — Project directory tracking and automatic context loading

• Added set_working_directory tool and project directory tracking: sessions now track a mutable ProjectDirectory in WorkingContext that persists across crash and restart. When a project directory is set, the session automatically discovers and loads the project's identity file (.netclaw/AGENTS.md, CLAUDE.md, AGENTS.md, or CONTEXT.md — first match wins) into the system prompt alongside global identity layers. The loaded project context is stable across turns and benefits from prompt caching. The set_working_directory tool validates that the target path exists and is within the audience's allowed file access roots; Public and Team audiences cannot use it by default. Also adds session_dir to the [session] context block. Closes Track session CWD in WorkingContext and emit as [working-context] + [project-instructions] #595, Resolve shell + file tool paths against session CWD #596.
