fix: update checking logic

fix: add support for gpt-5

Adds support for gpt-5 to the openai provider. Along with this change

warning to the user when max_length is reached. gpt-5 uses thinking inferred
from the max_tokens so we often hit max_length with a non trivial max_tokens
set.

fix: go releaser template
