CLI plugin inventory can report account-installed plugins as uninstalled

Start in codex-rs/cli/src/plugin_cmd.rs at run_plugin_list, then trace list_marketplaces_for_config and build_and_cache_remote_installed_plugin_marketplaces. Add focused CLI tests for configured, account, and combined scopes, preserving canonical marketplace identities, offline configured behavior, and explicit authentication or remote failures.

Codex variant

CLI. Observed on codex-cli 0.144.4 on Windows 11 / PowerShell 7.6. The configured-only list path is also present in release 0.144.5 and current main (1d941253e9354fe583a033660a6288df66e27488).

Behavior gap

codex plugin list reports configured marketplace snapshots, while account-backed installed plugins live in a separate remote inventory. When both inventories contain the same display name, the CLI can show an uninstalled configured entry while omitting the enabled account-installed entry. This makes a healthy installation look missing to users and diagnostics.

Concrete example:

• superpowers@openai-curated-remote 6.1.1 is account-installed and enabled.
• superpowers@openai-curated 5.1.3 is a distinct configured-marketplace entry and is not installed.

codex plugin list --available --json exposes only the second row. App-server plugin/installed exposes the first. Installing the configured 5.1.3 row would create a real duplicate and is not a valid repair.

Source-level cause

codex-rs/cli/src/plugin_cmd.rs::run_plugin_list calls PluginsManager::list_marketplaces_for_config(...), so its inventory is configured-only. Account installations are loaded separately through PluginsManager::build_and_cache_remote_installed_plugin_marketplaces(...) and app-server plugin/installed.

The two records have distinct canonical marketplace identities and must not be coalesced by display name.

Requested behavior

Please expose an explicit account-installed CLI inventory, for example:

codex plugin list --scope configured   # current default, unchanged and offline
codex plugin list --scope account      # account-installed/enabled inventory
codex plugin list --scope all          # both inventories, canonical IDs preserved

The exact command shape is flexible. The important compatibility requirements are:

• Existing invocations and configured-scope JSON retain their current shape and offline behavior.
• Account and combined output preserve marketplace provenance and return same-name identities separately.
• Missing authentication or a remote failure is explicit, never represented as installed: false.
• --available continues to apply only to configured catalog entries.

I traced the reusable manager API and can contribute focused CLI tests and an implementation. I have not opened a pull request because docs/contributing.md requires an explicit Codex-team invitation.
