fix: zone pool parser truncated every zone to its first entry

GoldRush.ZonePool separates zones with '; ' (semicolon + space) but the
node/bonus entry IDs within a zone with a bare ';'. BuildSites() split on
the bare ';', so each zone's entry list was cut down to its first ID --
which is always a herb. That is why events spawned a single wrong-zone
herb and no ore at all (PR #8).

Split on the two-character '; ' zone delimiter instead, so every zone
keeps its full node and bonus pools.

 ### Fixed
+- Zone pool parsing no longer truncates every zone to its first resource entry.
+  `GoldRush.ZonePool` separates zones with `"; "` (semicolon + space) but the
+  node/bonus entry IDs within a zone with a bare `";"`. `BuildSites()` split on
+  the bare `";"`, so each zone's entry list was cut down to its first ID — which

+  ore at all (reported in PR #8). The parser now splits on the two-character
+  `"; "` zone delimiter, so every zone keeps its full node and bonus pools.
 - Herb/ore categorization no longer guesses from display-name keywords. The old
   `SplitByCategory()` matched "lotus"/"clover"/"thorn"/"bloom" for herbs and
   "vein" for ore, which only worked for the original Northrend default pool and
