Use dark mode theme when launching from NeoVim's terminal with light mode

[tamlok]

Description

1. Windows Terminal is configured to use light mode theme.
2. Running opencode directly in Windows Terminal results in the usage of light mode theme in opencode.
3. Neovim forces to use light background.
4. Runs opencode in Neovim terminal, resultings in the usgae of dark mode theme in opencode.

Could we add an option to force using of the light mode of theme? Just like Neovim setting background to light or dark.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Light/Dark mode auto-switching #9697: [FEATURE]: Light/Dark mode auto-switching - Describes the same core issue where OpenCode doesn't detect or respect the terminal/system's light or dark mode preference

Feel free to ignore if none of these address your specific case.

No, they are not the same. If auto-detection is lacked or not working well, we need a way to specify it manually.
