fix: support xhigh reasoning effort for OpenAI models (#23545)

## Summary

Adds `xhigh` to the OpenAI reasoning effort normalizer so GPT-5.4 class
models can use `reasoning_effort: xhigh` without it being silently
dropped.

## Problem

The SDK schema (`codersdk/chats.go`) already advertises `xhigh` as a
valid `reasoning_effort` value, but the runtime normalizer in
`chatprovider.go` only accepts `minimal|low|medium|high` for the OpenAI
provider. When a user sets `xhigh`, `ReasoningEffortFromChat()` returns
`nil` and the value never reaches the OpenAI API.

## Changes

- **Fantasy dependency**: Updated `kylecarbs/fantasy` (cj/go1.25) which
now includes the `ReasoningEffortXHigh` constant
([kylecarbs/fantasy#9](https://github.com/kylecarbs/fantasy/pull/9)).
- **`chatprovider.go`**: Adds `fantasyopenai.ReasoningEffortXHigh` to
the OpenAI case in `ReasoningEffortFromChat()`.
- **`chatprovider_test.go`**: Adds `OpenAIXHighEffort` test case.
