codedb-pro: mcp__codedbpro__memo failed

failing tool: mcp__codedbpro__memo
redacted error excerpt: {"ok":false,"error":"memo: no entries"}

automated report from a graff session on a licensed codedb-pro tool failure

details were redacted at the source

Same class as #609: these are model-argument mistakes being auto-filed as CodeDB Pro defects. 811693e extends the caller-error classifier (missing 'file' joins missing 'hash') so they open the native fallback instead of filing reports here. If you hit a real memo failure after this (not a missing-argument error), reopen with the unredacted error shape.

[justrach]

Closing as stale: memo: no entries is an empty-memo state, not a CodeDB Pro defect, and the body was redacted at source so there is nothing actionable (sibling #510 was closed the same way). One follow-up worth a line: no entries is not yet in the caller-error needle list in src/codedbpro_paths.zig, so this shape could auto-file again until that is added.
