v4.7.1

Two fixes found by dogfooding solumbe in Claude Code. No command or field was removed.

Fixed

• A path-less MCP call no longer hangs a server that runs from / or the home directory. Claude Desktop starts its configured MCP servers with no working directory, so they run from /, and Claude Code sessions in the desktop app can be routed to that instance. A context_pack (or any tool that takes a repository path) called without path then scanned the whole filesystem: the host reported "Request timed out" and the call failed with a RangeError minutes later. Such a call now answers at once with -32602 and says to pass path. An explicit path, and tools that take none, are unchanged.
• A question about the code reads as explain, not unknown. Where is X handled, how does Y work, why does Z, which file registers W and is A consistent with B? named no action word, so the heuristic intent came back unknown with the ambiguous-action open question, and where is X implemented came back add. A question-shaped request is now explain, or debug when it asks about a symptom (why does checkout crash?). A question addressed to I, we or you (how do I add a route) is still read from its action word, and why is a stop word. The reads suite gains five cases; the heuristic's intent accuracy on it goes from 0.517 to 0.793 (23 of 29). Check X against Y and compare X with Y still read as unknown.
