/**
 * @file server-s3-cc-config.test.js
 * @description Settings for members (S3 plan, P6): a non-admin manages THEIR
 * OWN Claude Code configuration through `/api/cc-config`. Covers the router's
 * own allowlist gate (`cc-target.js` — no `/profiles*`, no
 * `/plugins/update-all`, nothing unlisted), the one target resolver (a
 * member's `~/.claude`, an admin's host home unchanged, 403 ENOACCOUNT for a
 * developer with no account — never the host's), every file write running AS
 * the member through `write-as` with the content on stdin (skills, settings,
 * keybindings, backups), `claude plugin|mcp …` run as the member's sudo argv
 * (no `-y`, user scope only, no env/headers across sudo), project writes only
 * in the member's own workspaces, an admin's project-memory create in a
 * member's folder written as that member, and a member's change broadcast to
 * that member alone. A fake passwd (every member = this test's uid),
 * server.conf, fake sudo (run-as) and a fake `claude` spawn make it run
 * without root.
