rka-oai 752ed90d78 current time reminders impl for system clock (varlatency 2/n) (#28824) ...

Stacked on #28822.

## Summary

- add a host-injectable current-time provider with a built-in system
implementation
- record UTC developer reminders in history immediately before due model
requests
- keep cadence state per session and force a refresh after compaction

This does NOT include the app server client <-> server clock logic. This
PR is only for the reminder message & system clock that will be used in
prod.

## Testing

- `just test -p codex-core varlatency_`
- `just clippy -p codex-core -p codex-app-server -p codex-mcp-server -p
codex-thread-manager-sample`
- `just fmt`
