Add C_GameObjectInfo (GetGameObjectInfoByID + RequestLoadGameObjectByID)

GameObject analog of C_CreatureInfo, reading the gameobject cache
(gameobjectcache.wdb, SMSG_GAMEOBJECT_QUERY_RESPONSE):
- GetGameObjectInfoByID -> { gameObjectID, name, type, displayID } | nil
  (synchronous peek)
- RequestLoadGameObjectByID -> bool, fires GAMEOBJECT_DATA_LOAD_RESULT
  when an uncached GO arrives.

The GO cache is a sibling class of the creature cache: same hash-map
shape but a different vtable and a larger entry (loaded flag at
entry+0x98 vs +0x50), so it has its own _GetRecord (FUN_00558560) and
response parser (FUN_005588E0). Generalized Cache::QueryLoad to take a
per-cache _GetRecord via Register and to hook BOTH parsers (creature +
gameobject), dispatching completion by cache instance. Renamed the
creature offsets FUN_CACHE_* -> FUN_CREATURE_* now that "generic" was a
misnomer.

GO field offsets: name@+0x08 verified (FUN_0062dc10 reads [block+0x08]),
type@+0x00 / displayID@+0x04 from the wire/WDB order. Verified in-game:
Mesa Elevator 47297 type 11 displayID 360, Windrunner 176250 type 15
displayID 7087, and RequestLoadGameObjectByID populated an uncached GO
("Lighting Impact Large", type 5). Creature path re-verified after the
refactor (GetCreatureInfoByID + the load event still work).

+### `ExportDBCFiles` (console command)
+
+A ClassicAPI-original companion to `ExportInterfaceFiles` that dumps
+every `.dbc` table the client loads to `DBFilesClient\` under the working
+directory (next to `WoW.exe`). No subcommand — there's only one thing to
+export.

+ExportDBCFiles: wrote 155 .dbc file(s) to DBFilesClient\
+```
+
+Unlike the MPQ `(listfile)` alone (which omits ~18 of the tables the
+client actually loads — mostly cosmetic animation/sound/lookup DBCs that
+Blizzard left out of the index), this unions two sources for a complete
+set:
+
+1. the **MPQ `(listfile)`** under `DBFilesClient\` — catches files that
+   ship in the archives without a loader (e.g. `wowerror_strings.dbc`);
+2. a **`.text` scan for the DBC path-getter pattern**
+   (`mov eax, &"DBFilesClient\X.dbc"; ret`) — the authoritative list of
+   what this build loads. The master DBC init (`FUN_0053f8b0`) is
+   straight-line with no iterable name table, so the per-DBC getters
+   *are* the registry; scanning for them is the same technique that
+   built [docs/DBCs.md](DBCs.md).
+
+Results are deduped case-insensitively. Handy for a local DBC dump to
+inspect schemas/values directly — e.g. verifying a record's column
+layout against a known row, the way `C_Item.GetEnchantInfo`'s effect
+columns were confirmed — without a standalone MPQ extraction tool.

+1.12 packs the entry ID directly into bits 24-47 of the 64-bit
+GUID for the types that carry one; this function does the shift
+and mask so addons don't have to.
+
+```lua
+C_CreatureInfo.GetCreatureID(UnitGUID("target"))   -- 1842 for Hogger
+C_CreatureInfo.GetCreatureID(UnitGUID("pet"))      -- pet's creature template ID
+C_CreatureInfo.GetCreatureID(UnitGUID("player"))   -- nil (no entry on players)
+```
+
+Accepts creature GUIDs (`0xF130xxxx…`) and pet GUIDs
+(`0xF140xxxx…`). Returns `nil` for:
+- non-string input or malformed GUIDs
+- player GUIDs — the low 32 bits hold a player ID, not a template
+- game-object / dynamic-object / corpse / item GUIDs — modern's
+  `C_CreatureInfo` doesn't surface entry IDs for these even though
+  the bits are in the same range; addons that need them can shift
+  the raw GUID themselves (`(guid >> 24) & 0xFFFFFF`)
+- entry IDs of 0 — the engine never assigns 0; treated as "no info"
+
+The standard 16-digit (`"0xHHHHHHHHLLLLLLLL"`) and 8-digit
+(`"0xLLLLLLLL"`) GUID-string forms are both accepted, the same forms
+the `C_PlayerInfo.GUIDIs*` functions take.
+
+The creatureID this returns is exactly what
+[`C_CreatureInfo.GetCreatureInfoByID`](#c_creatureinfogetcreatureinfobyidcreatureid)
+takes — `GetCreatureInfoByID(GetCreatureID(UnitGUID("target")))` gives
+the target's cached name/type/family/rank.
+
+### `C_CreatureInfo.GetCreatureInfoByID(creatureID)`
+
+Reads the client-side **creature cache** (`creaturecache.wdb`, fed by
+`SMSG_CREATURE_QUERY_RESPONSE`) for an NPC/creature by ID and returns a
+table — or `nil` if it isn't cached:
+
+```lua
+local info = C_CreatureInfo.GetCreatureInfoByID(61332)
+-- {
+--   creatureID = 61332,
+--   name       = "Misthoof Stag",
+--   subName    = "",     -- title/subtitle ("" if none)
+--   type       = 1,      -- CreatureType: 1=Beast, 7=Humanoid, …
+--   family     = 0,      -- CreatureFamily
+--   rank       = 0,      -- 0=normal, 1=elite, 2=rareelite, 3=worldboss, 4=rare
+--   displayID  = 10957,  -- model display ID
+-- }
+```
+
+This is a synchronous **peek** — it returns data only for creatures
+already cached (seen this session, or loaded from `creaturecache.wdb`
+at login), and `nil` otherwise. Unlike `UnitCreatureType`/
+`UnitClassification`, which only work on a *live unit token*, this
+answers for any creatureID you have cached — even one not currently in
+the world.
+
+Reads through the engine's generic cache `_GetRecord` (with no callback,
+so it's a pure lookup — no network query) and pulls the fields straight
+off the cached data block. Field offsets verified against the binary
+(rank read by the engine's classification helper at `[block+0x20]`) and
+real `creaturecache.wdb` rows (Misthoof Stag→type 1, Nordrassil
+Nymph→type 7 rank 1, Greathorn Hunter→family 26).
+
+For a creature that isn't cached yet, call
+[`RequestLoadCreatureByID`](#c_creatureinforequestloadcreaturebyidcreatureid)
+first and read it once `CREATURE_DATA_LOAD_RESULT` fires.
+
+### `C_CreatureInfo.RequestLoadCreatureByID(creatureID)`
+
+Asynchronously fetches a creature that isn't in the cache yet — issues
+`SMSG_CREATURE_QUERY` and fires **`CREATURE_DATA_LOAD_RESULT(creatureID,
+success)`** when the response lands, at which point
+[`GetCreatureInfoByID`](#c_creatureinfogetcreatureinfobyidcreatureid)
+returns its data. The same shape as
+[`C_Item.RequestLoadItemData`](#c_itemrequestloaditemdatabyiditem--c_itemrequestloaditemdataitemlocation).

+        -- info.name, info.type, info.rank, …
+    end
+end)
+
+C_CreatureInfo.RequestLoadCreatureByID(10184)   -- Onyxia → fires the event,
+                                                --  then GetCreatureInfoByID works
+```
+
+Returns `true` if the request was accepted (`false` only on bad input
+or a full pending set). If the creature is **already** cached, the
+event fires synchronously with `success = true`. On a query that never
+resolves it fires once with `success = false` after a timeout.
+
+Implementation: a shared `Cache::QueryLoad` dispatcher hooks the engine's
+generic cache response parser (`FUN_00556E20`) **once** and routes by
+cache instance — the same hook serves the gameobject cache too. The
+creature/gameobject caches use this generic parser; the item and quest
+caches have their own, so there's no hook collision. Verified in-game: `RequestLoadCreatureByID(10184)` on
+an uncached Onyxia fired the event and populated the cache (type 2
+Dragonkin, rank 3 world boss).
