Since Clojure 1.11 (CLJ-2603), associative destructuring of a sequence containing a single map binds directly to the map's contents. Verified against core.clj destructure/pmap function (lines 4472-4476): when the value is a seq with exactly one element, it uses (first gmap) directly rather than treating the seq as alternating key-value pairs. Fixes clojure#688

Adds a subsection to the Destructuring guide explaining that since Clojure 1.11 (CLJ-2603), associative destructuring of a sequence containing a single map binds directly to the map's contents.
Includes examples showing both the singleton behavior and the traditional multi-element alternating key-value behavior.
