Brues 108a91a843 feat(api): describe the API in the code, browse it with /classicapi
docs/API.md is 18.7k lines and its anchors are signature slugs, so editing a
signature breaks the 281 internal and 88 README links into it. Blizzard
solved the same problem by shipping the API as data plus a browser addon,
and warcraft.wiki.gg renders those same tables. One set of descriptors can
feed all three.

Each registration now carries one next to it: typed arguments and returns,
nilability, defaults, and a sentence. Events, enumerations and returned table
shapes are described the same way. No Script_* body changed.

Game.h gains namespace Game::Doc (Field with Req/Opt/Vararg, FieldList,
Function, Method, Structure, Event) and a trailing descriptor argument on all
six Game::Lua::Register* plus Event::Custom::AutoReserve.

api/Documentation.cpp records every registration on the first pass of each
Lua state and seals it, so /reload re-registers but records nothing and the
environment comes from which pass saw the name. Export is lazy: nothing is
materialized until C_APIDocumentation.GetSystem asks for one system, because
eager export would build thousands of tables per reload for a slash command.
_classicapi_UndocumentedAPI lists what still has no descriptor.

AddOns/!!!ClassicAPI/APIDocumentation/ ports Blizzard_APIDocumentation's eight
files. Named /classicapi, not /api: the browser holds only what ClassicAPI
adds, so /api would have implied the whole 1.12 surface. Two deliberate
differences from the retail source, both noted in the file headers: a system
search also matches its namespace, since that is the name people type; and an
undocumented function says so, because an empty signature otherwise reads as
a real one.

LinkUtil gains the SetItemRef to LinkUtil.ProcessLink dispatch. That handler
registry was dead code; a new link type now registers a handler instead of
stacking another SetItemRef override. Also defines assertsafe there, which
was undefined and only mattered once the function went live.

Documented: the C_Spell and C_SpellBook surface, the spell globals, both
spellbook enumerations, the 13 UNIT_SPELLCAST_* events, GameTooltip as the
widget-method example and C_Glue as the glue and mixed-environment example.
66 of 692 function registrations. tools/New-ApiDocSkeletons.ps1 emits
paste-ready skeletons to make the rest of the sweep tractable.

Verified in game: the browser lists, searches, and prints detail; links
render and click through; right-click copies and shift-click dumps.
