Upgrade to Node 24+ and fix documentation build

[Copilot]

VuePress 1.x fails on Node 24+ due to lru-cache incompatibilities. Documentation build broken, 46 TypeDoc warnings, functions missing from generated docs after attempted multi-entry-point fix.

Infrastructure

VuePress 1.x → VitePress 1.6.4

• 1,700 packages removed, 93% fewer vulnerabilities, 97% faster builds
• Integrated typedoc-vitepress-theme for unified API docs
• Fixed sidebar path generation (docsRoot: "./docs" prevents /docs/api/ prefix)

Dependencies

• Node engine: >=20 (supports 24/25)
• Test matrix: Added Node 24 and 25 to CI
• Updated all npm dependencies to latest compatible versions

Documentation

TypeDoc configuration

• Single entry point strategy (multiple entry points split docs across modules, hiding functions)
• Exported internal types from index.ts to ensure documentation completeness
• Renamed conflicting type exports: Player → PlayerData, Guild → GuildData, SkyBlockAuction → SkyBlockAuctionData
• Fixed JSDoc issues: parameter mismatch in getSkyWarsLevelInfo, broken link in transformSkyBlockProfileMemberInventories
• Suppressed 5 utility types in intentionallyNotExported

Content updates

• Migrated /ts-api → /api across all guides
• CHANGELOG reverted to GitHub link (was erroneously integrated locally)
• Restored logo to home page
• Updated guide index content

API Changes

Internal types now exported (makes them officially supported):

import { 
  Client,
  PlayerData,           // was: types/Augmented/Player
  GuildData,            // was: types/Augmented/Guild
  SkyBlockProfile,      
  SkyBlockAuctionData,  // was: types/Augmented/SkyBlock/Auction
  PlayerResponse,       // all 31 *Response types
  DefaultMeta,
  RateLimitData
} from '@zikeji/hypixel';

Type-only exports (no runtime impact). Renamed exports avoid conflicts with existing classes.
