[BUG] applyCaching overrides previous provider options

[dpuyosa]

Description

transform.applyCaching overrides previous providerOptions like the one set in transform.normalizeMessages for openaiCompatible.

Plugins

OpenCode version

Steps to reproduce

For example have a OpenaiCompatible provider with a Claude model and interleaving.

The interleaving is supposed to add a providerOption with the reasoning part in transform.normalizeMessages, but it doesnt appear in the final prompt.

Fixed: applyCaching now deep-merges providerOptions so earlier normalizeMessages options (e.g., openaiCompatible reasoning) are preserved. Commit: 45515ab.
