aiwg/tools/cli/update.mjs

Deployment tool and support utility for AI context. Copies agents, skills, commands, rules, and behaviors into the paths each AI platform reads (Claude Code, Codex, Copilot, Cursor, Warp, OpenClaw, and 6 more) so one source of truth works across 10 platfo

/**
 * AIWG Update Command
 *
 * Handles channel-aware package updates invoked by `aiwg sync --channel <name>`.
 *
 * Supported channels:
 *   latest   — stable npm release   (npm install -g aiwg)
 *   next     — alpha/beta/RC        (npm install -g aiwg@next)
 *   nightly  — nightly snapshots    (npm install -g aiwg@nightly)
 *   (none)   — stays on current channel, updates in place
