Codex background delegation

This support skill changes Codex's waiting boundary. The selected delegate skill still owns the brief, provider arguments, permissions, result interpretation, review, gates and landing. Claude's background Bash workflow stays unchanged. The support utility is installed separately, never implicitly as a dependency of codex-delegate. Details: references/configuration.md.

First use / setup

If the delegate_run tool is not available, setup is incomplete. Tell the user that bootstrap will update $CODEX_HOME/config.toml (default ~/.codex/config.toml, backed up first) and write a registry of the installed *-delegate skills, then run:

node "<skill-dir>/scripts/bootstrap.mjs"
