📝 Walkthrough

Walkthrough

This pull request removes sharding support from the discord.js client, introduces browser-fingerprinting headers via SuperProperties in the REST layer, and refactors the WebSocket layer to support user accounts through a new capabilities system. The client constructor now defaults to an empty options object, gateway fetches return only a URL, and identify payloads are restructured without intents or shard information.

Changes

Cohort / File(s)	Summary
Client Sharding Removal packages/discord.js/src/client/Client.js, packages/discord.js/src/index.js, packages/discord.js/src/sharding/ShardingManager.js	Removes GatewayIntentBits, ShardClientUtil usage; shard property now always null. Auto-shard calculation removed; throws error when amount is 'auto'. Removes fetchRecommendedShardCount from public exports.
Options & Utilities packages/discord.js/src/util/Options.js, packages/discord.js/src/util/Util.js	Adds default online presence to ClientOptions. Removes fetchRecommendedShardCount function and userAgentAppendix composition. Simplifies option validation by removing explicit intents and presence checks.
REST Browser Fingerprinting packages/rest/src/lib/REST.ts, packages/rest/src/lib/utils/browser-headers.ts, packages/rest/src/lib/utils/super-properties.ts, packages/rest/src/lib/utils/constants.ts, packages/rest/src/lib/utils/types.ts, packages/rest/src/shared.ts	Introduces SuperProperties class for constructing user-agent and browser headers with base64 encoding and build-number fetching. Adds generateBrowserHeaders utility. Updates REST request headers to merge browser fingerprinting when superProperties is available. Changes authPrefix default from 'Bot' to empty string. Exports new browser and super-properties utilities.
WebSocket Capabilities System packages/ws/src/index.ts, packages/ws/src/utils/capabilities.ts, packages/ws/src/strategies/context/IContextFetchingStrategy.ts, packages/ws/src/utils/constants.ts	Introduces CapabilityFlags enum and Capabilities class for bitfield operations. Adds UserPresenceData and UserIdentifyData interfaces for user-style identify payloads. Replaces intents with capabilities throughout. Updates default presence to online state and identify properties to use SuperProperties. Removes intents from fetching strategy options.
WebSocket Manager & Shard Simplification packages/ws/src/ws/WebSocketManager.ts, packages/ws/src/ws/WebSocketShard.ts	Simplifies gateway information fetch to return only \{ url: string \}; removes shard count calculation and session_start_limit validation. Removes GatewayIntentBits, GatewayIdentifyData, and related bot-specific types. Updates identify payload to UserIdentifyData without shard array or intents. Relaxes token handling to allow overwriting. Defaults to single shard if shardIds not provided.
