working config `proxies` is not a sequence, append skipped

Error message

working config `proxies` is not a sequence, append skipped

What it means

During composition, the extracted proxies must be appended to the working config's `proxies` field, but that field exists and is not a sequence. The append is skipped and the working config is returned unchanged, with a warning logged — extracted member proxies are dropped.

Solutions

1. Fix the base/working profile so `proxies` is a list (or remove the key so it is created fresh)
2. Re-derive the working config from a known-good base profile
3. Add schema validation of the working config before composition
4. Check earlier merge/enhance steps for rules that overwrite `proxies` with a non-list

Example fix

# before (working config)
proxies:
  enabled: true
# after
proxies: []

fn working_proxies_ok(working: &ConfigValue) -> bool {
    obj_get(working, "proxies").map_or(true, |v| v.as_array_arc().is_some())
}

fn is_array_field(config: &ConfigValue, key: &str) -> bool {
    obj_get(config, key).map_or(true, |v| v.as_array_arc().is_some())
}

if !working_proxies_ok(&working) {
    log::warn!("working proxies corrupted; resetting to [] before compose");
    let working = obj_insert(working, "proxies", ConfigValue::Array(Arc::from(vec![])));
}

When it happens

Trigger: append_proxies: the working config has a `proxies` key but working.as_array_arc() (via the match) fails — `proxies` in the accumulated working document is a non-array value (e.g. an object left over from a bad merge).

Common situations: A prior composition/merge step replaced `proxies` with a mapping; a base profile with `proxies` corrupted by manual editing or a bad enhancement/patch; loading a working config from a source emitting a different schema.
