Add hexai config to dotfiles (Linux only)

Manage ~/.config/hexai/config.toml from the dotfiles repo, mirroring how
helix, lazygit, and opencode are handled. The home_hexai task is
gated to Linux because hexai is currently only used on the Linux
workstation.

The deployed config sets Ollama Cloud (kimi-k2.6 at https://ollama.com)
as the default provider and uses gemma4:31b for in-code completion.
The API key is read from $HEXAI_OLLAMA_API_KEY (or $OLLAMA_API_KEY).
