fix(llms): skip reasoning_effort patch for *-chat-latest models

Browse Source 
normalizeModelName reduces gpt-5.2-chat-latest to gpt-52-chat-latest,
which matches the gpt-52 prefix and gets reasoning_effort='none'.
But chat-latest models don't support reasoning_effort, causing
HTTP 400.

Fix: check for 'chat-latest' before applying reasoning_effort patches.

Fixes #563
