[Harlowe] Click macros that affect named hooks don't work if the hook hasn't been output yet

[daterre]

See the following example.

[First]<s1|
(click: ?s1)[Second]<s2|
(click: ?s2)[Third]<s3|
(click: ?s3)[Last]

The result is that Second doesn't become a link and therefore Third and Last can never be generated. The reason is that HarloweStoryFormat tries to enchant the hooks links immediately. It should wait for the story to Idle and then process the enchantments.

A temporary, albeit quite ugly, workaround:

(link-replace: "First")[(link-replace: "Second")[(link-replace: "Third")[Last]]]
