Supertag CLI v2.5.10

Fixed

• tana_semantic_search crashed on nodes with a null name (null is not an object (evaluating 'name.includes')). enrichSearchResults copied the nullable nodes.name column straight into the result, then isReferenceSyntax() called .includes() on it — so any result set containing an unnamed source/container node failed the entire search (retrying with a different query sometimes dodged the bad node). Fixed at the source (coalesce null name → "" during enrichment) and hardened isReferenceSyntax() to treat null/undefined/empty as non-reference. The shared enrichment/filter (src/embeddings/search-filter.ts) is used by the MCP tana_semantic_search tool and the CLI (search, embed), so both are covered. Also guarded the webhook server's semantic-result renderer (convertSemanticResultsToTana), which had the same unguarded .includes on a nullable node/ancestor name. (Reported via Claude Code.)
