Release: v0.15.3

Changes

• Scope filter for searches (opt-in). query_documents (MCP) and the query CLI accept an optional scope to limit a search to one or more path prefixes — useful when a single database holds multiple corpora. Pass one prefix or a list (results are unioned); matching is exact-or-descendant, so /docs/api matches /docs/api/auth.md but not /docs/apiv2. The CLI adds a repeatable --scope flag. Prefixes must be absolute in the server's OS path style — relative prefixes match nothing. Optional and backward compatible: omitting scope is unchanged.
• Clearer MCP tool descriptions. Tool and parameter descriptions now document their return shapes and are corrected to match actual behavior (status no longer lists fields it does not return), so MCP clients can use the tools correctly without the bundled skill installed.
