fix: snippet.list tag filter (same array-binding bug as memory.list) (#1)

Replace the raw `${snippets.tags} @> ${tags}::text[]` template with
Drizzle's arrayContains, matching the memory.list fix. The raw template
expanded the JS array into positional params, producing a malformed
array literal (one tag) / record-cast error (two tags) at runtime.
