[codex] Populate remote plugin local versions (#29956)

# What

- Carry installed remote release versions through remote plugin
summaries as `localVersion`.
- Keep the app-server mapping a pure adapter by populating that value in
the remote catalog layer.

# Why

Remote plugin summaries always returned `localVersion: null` even after
their versioned bundles had been installed locally. Consumers such as
scheduled-task template discovery use `localVersion` to resolve a
plugin's materialized root, so templates from remote curated plugins
were silently skipped.
