+Clear all reactive text property watchers and dependencies, without affecting layer definitions.
+
+This is useful when you want to remove all reactive bindings but keep the layer definitions intact.
+
+**Examples:**
+
+```elisp
+;; Define a reactive layer
+(progn
+  (defvar my-reactive-color "red")
+  (tp-define-layer reactive-layer
+    :props (face (:foreground $my-reactive-color)))
+  ;; Clear reactive bindings only
+  (tp-reactive-reset)
+  ;; Layer still exists, but changing my-reactive-color no longer updates it
+  (tp-layer-props 'reactive-layer))
+;; => (face (:foreground "red") tp-name reactive-layer)
