Charley Cunningham 4c1744afb2 Improve Plan mode reasoning selection flow (#12303) ...

Addresses https://github.com/openai/codex/issues/11013

## Summary
- add a Plan implementation path in the TUI that lets users choose
reasoning before switching to Default mode and implementing
- add Plan-mode reasoning scope handling (Plan-only override vs
all-modes default), including config/schema/docs plumbing for
`plan_mode_reasoning_effort`
- remove the hardcoded Plan preset medium default and make the reasoning
popup reflect the active Plan override as `(current)`
- split the collaboration-mode switch notification UI hint into #12307
to keep this diff focused

If I have `plan_mode_reasoning_effort = "medium"` set in my
`config.toml`:

If I don't have `plan_mode_reasoning_effort` set in my `config.toml`:
