## Summary
- Add a remote plugin install write call that POSTs the selected remote
plugin to the ChatGPT cloud plugin API.
- Align remote install with the latest remote read contract:
`pluginName` carries the backend remote plugin id directly, for example
`plugins~Plugin_linear`, and install no longer synthesizes
`<name>@<marketplace>` ids.
- Validate remote install ids with the same character rules as remote
read, return the same install response shape as local installs, and
include mocked app-server coverage for the write path.
## Validation
- `just fmt`
- `cargo test -p codex-app-server --test all plugin_install`
- `cargo test -p codex-core-plugins`
- `just fix -p codex-app-server`
- `just fix -p codex-core-plugins`
Add a temporary internal remote_plugin feature flag that merges remote
marketplaces into plugin/list and routes plugin/read through the remote
APIs when needed, while keeping pure local marketplaces working as
before.

Split plugin loading, marketplace, and related infrastructure out of
core into codex-core-plugins, while keeping the core-facing
configuration and orchestration flow in codex-core.
