A new environment variable lets you inject per-content-hash skill and plugin attribution into command and skill telemetry.
A new CLAUDE_CODE_SKILL_ATTRIBUTION env var lets a caller inject per-content-hash skill and plugin attribution (skill_id, plugin_id) into telemetry, mirroring the existing CLAUDE_CODE_PLUGIN_ATTRIBUTION mechanism. It feeds a new CX() attribution helper used across command and skill telemetry events. Entries that aren't a JSON object are ignored.
