## What changed
- Recognize `edu_plus` and `edu_pro` as distinct education workspace plans across authentication, backend rate-limit mapping, and app-server account schemas.
- Include both plans in cloud configuration eligibility and use the education usage-limit behavior.
- Display the plans as `Edu Plus` and `Edu Pro` in the TUI status view.
## Testing
- Cover parsing, workspace classification, account and rate-limit responses, cloud configuration eligibility, usage-limit messages, and TUI display names for the new variants.

## Why
Background refreshes previously warmed only the on-disk cache, so new sessions in the same process continued using the startup snapshot.
## What changed
- Make `CloudConfigBundleLoader` retrieve the latest shared bundle on each configuration load.
- Update the in-memory bundle after successful refreshes while preserving the last successful bundle when a refresh fails.
- Stop refresh work when its loader is replaced or its final clone is dropped.
## Testing
- Cover refreshed requirements and managed configuration in later sessions.
- Cover concurrent initial loads, refresh failures and recovery, bundle clearing, and refresh-task cancellation.

## Summary
- Increase the cloud config bundle background refresh interval from 5
minutes to 15 minutes.
- Increase the local cloud config bundle cache TTL from 30 minutes to 1
hour.
## Why
- Reduce background cloud config fetch frequency while keeping cached
workspace-managed policies available longer between refreshes.
## Validation
- `just fmt`
- `cargo test -p codex-cloud-config`
## Summary
Allow EDU ChatGPT workspaces to fetch cloud config bundles. The existing
cloud config eligibility gate only allowed business-like and enterprise
plans, which meant EDU admins could configure managed policies in the UI
but the Codex client would skip fetching them.
This keeps individual/pro and team-like usage-based plans excluded, and
adds service-level coverage for both `edu` and `education` plan aliases.
## Validation
- `just fmt`
- `just test -p codex-cloud-config`
- Built the Codex app locally, created a new EDU ChatGPT workspace, and
verified config bundles can be fetched and are properly applied.
## Summary
- Splits the monolithic `codex-cloud-config` implementation into focused
modules.
- Keeps behavior unchanged from the preceding config bundle runtime
switch.
## Details
This is the reviewability follow-up after the lineage-preserving
migration PRs. The split separates backend transport, loader
construction, cache handling, metrics, validation, service
orchestration, and focused tests into named files.
Verification: `just fmt`; `just test -p codex-cloud-config`.
