// ---------------------------------------------------------------------------
// 0702 — CLI paths (`vskill keys set/list/remove/path`) + env-var override.
//
// Covers:
//   - `vskill keys set <provider>` persists via piped stdin
//   - `vskill keys list` reflects files saved via both CLI and API
//   - `vskill keys path` output matches the server's /api/settings/storage-path
//   - `vskill keys remove <provider>` is reflected in the modal after refresh
//   - Real env var (ANTHROPIC_API_KEY) OVERRIDES the stored key, so available
//     provider status is true even with no file entry
//   - chmod 0600 on POSIX
//
// CLI-only tests run WITHOUT a browser (faster). The one cross-check test
// launches a server + browser to confirm UI reflects CLI removals.
