## Why
Cold resumes and forks could lose the thread's active permission profile and
fall back to the current configured default.
## What changed
- Restore the latest persisted approval policy, approvals reviewer, and active
permission-profile ID when resuming or forking a thread.
- Re-resolve persisted profile IDs through current configuration and
requirements. Missing or invalid profiles fall back to the configured
default, while threads without a persisted profile continue to use current
configuration.
- Keep explicit permission and approval overrides ahead of persisted settings.
## Testing
Added coverage for legacy and paginated histories, settings updates, explicit
overrides, removed or changed profiles, requirement fallbacks, and forks.

## What changed
- Keep the configured `approvalPolicy` when a model in
`auto_review.required_on_models` selects the `auto_review` reviewer.
- Continue downgrading full-access sessions to workspace-write and rejecting
incompatible reviewer overrides.
## Testing
- Cover supported approval policies across thread start, settings updates,
turn-time model switches, resume, and fork flows.

## What changed
- Add the managed `auto_review.required_on_models` requirement, unioning model slugs across requirement layers and exposing the result through `configRequirements/read`.
- Force listed models to use `on-request` approvals with the `auto_review` reviewer. Downgrade Full Access to workspace-write when starting a protected session, and reject incompatible runtime overrides or use when automatic review is disabled.
- Preserve these protections across thread starts, resumes, forks, model changes, turn overrides, MCP approvals, and TUI session attachment.
## Testing
- Add coverage for layered model requirements and exact provider-alias matching.
- Add app-server tests for protected thread lifecycle operations, unsafe setting overrides, legacy thread upgrades, disabled automatic review, and requirements API output.
