perf: openai-curated marketplace scan appears to enumerate a very large not-installed catalog every turn

Summary

codex plugin marketplace list appears to enumerate the full openai-curated catalog on every run, including more than 150 not installed plugins. This creates unnecessary scanning and log noise during startup and diagnostics.

Reproduction

• Run codex plugin marketplace list
• Observe that openai-curated is included alongside openai-primary-runtime and openai-bundled
• Run codex plugin list
• Only 7 plugins are actually installed/enabled in this environment:
• documents@openai-primary-runtime
• pdf@openai-primary-runtime
• spreadsheets@openai-primary-runtime
• presentations@openai-primary-runtime
• template-creator@openai-primary-runtime
• browser@openai-bundled
• sites@openai-bundled
• The openai-curated marketplace still expands into a large list of not installed entries, including ngs-analysis@openai-curated

Related diagnostic warning

codex doctor also reports an update-check mismatch:

• running package root: <codex-install>/npm-openai-codex/0.142.5/node_modules/@openai/codex
• npm package root: <node-install>/node_modules/@openai/codex

npm config get prefix -g returns <node-install>.

Impact

• The curated catalog is scanned even though the environment only uses a small installed subset.
• There is no obvious safe ~/.codex/config.toml key to disable openai-curated as a source.
• The repeated catalog expansion seems unrelated to the few installed plugins and looks like avoidable work.

Environment

• Codex CLI 0.142.5
• Windows 11 / PowerShell 7 / mise-managed npm install
• npm:@openai/codex installed under mise
