## Summary
- Preserve app declaration order when loading plugin .app.json files.
- Keep plugin connector summaries in plugin app order after connector
metadata is merged and filtered.
- Add regression coverage for .app.json order and connector summary
order.

## Why
Windows can reject plugin cache upgrades when a running MCP server still
has its working directory inside the currently active plugin version.
The existing cache refresh path replaces
`plugins/cache/<marketplace>/<plugin>` as a whole, so a live handle
under the old version can make an otherwise ordinary version bump fail.
This PR keeps the existing plugin-selection model intact while making
version bumps less disruptive.
## What changed
- When installing a new version beside an existing plugin cache root,
move only the staged version directory into place instead of replacing
the whole plugin root.
- Best-effort prune older sibling version directories after the new
version is activated.
- Preserve the existing whole-root replacement path for first installs
and same-version refreshes.
- Add regression coverage for upgrading from `1.0.0` to `2.0.0` without
replacing the plugin root.
## Verification
- `cargo test -p codex-core-plugins install_with_new_version`
- `cargo fmt --package codex-core-plugins --check`
Supersedes the abandoned #19859, rebuilt on latest `main`.
# Why
PR #19705 adds discovery for hooks bundled with plugins, but `/plugins`
still only shows skills, apps, and MCP servers. This follow-up makes
bundled hooks visible in the same plugin detail view so users can
inspect the full plugin surface in one place.
We also need `PluginHookSummary` to populate Plugin Hooks in the app;
`hooks/list` is not enough there because plugin detail needs to show
hooks for disabled plugins too.
# What
- extend `plugin/read` with `PluginHookSummary` entries for bundled
hooks
- summarize plugin hooks while loading plugin details
- render a `Hooks` row in the `/plugins` detail popup

## Summary
- Add best-effort auto-upgrade for user-configured Git marketplaces
recorded in `config.toml`.
- Track the last activated Git revision with `last_revision` so
unchanged marketplace sources skip clone work.
- Trigger the upgrade from plugin startup and `plugin/list`, while
preserving existing fail-open plugin behavior with warning logs rather
than new user-visible errors.
## Details
- Remote configured marketplaces use `git ls-remote` to compare the
source/ref against the recorded revision.
- Upgrades clone into a staging directory, validate that
`.agents/plugins/marketplace.json` exists and that the manifest name
matches the configured marketplace key, then atomically activate the new
root.
- Local `.agents/plugins/marketplace.json` marketplaces remain live
filesystem state and are not auto-pulled.
- Existing non-curated plugin cache refresh is kicked after successful
marketplace root upgrades.
## Validation
- `just write-config-schema`
- `cargo test -p codex-core marketplace_upgrade`
- `cargo check -p codex-cli -p codex-app-server`
- `just fix -p codex-core`
Did not run the complete `cargo test` suite because the repo
instructions require asking before a full core workspace run.
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.
