Poe: add GLM-5 model

[gjtiquia]

this is still a draft PR, im hoping to get the ok from @fhennerkes and @kamilio before marking it as ready for review edit: ready for review

i noticed from https://poe.com/api/models that glm-5 is available via Novita AI, and i would like to try out using glm-5 using Poe as a provider on Opencode, which pulls its models from models.dev

as much as possible i followed the existing conventions for other GLM models provided by Poe via Novita AI, but i cant help but notice a few things

• glm-4.7 should be deprecated in favor of glm-4.7-n according to https://poe.com/api/models. glm-4.7 is broken on Opencode while glm-4.7-n works.
• other GLM providers have set temperature = true and open_weights = true, whereas Poe has them set to false. is that accurate or should Poe change these fields to be consistent with other providers as well?

i dont mind helping to address these issues, either in this PR or in separate PRs

this PR references

• Add Poe.com as provider #374
• Poe: adding Gemma-4-31B (free model) #1374

thanks for all the great work!

Hi! I think for this model you could set temperature to True as it explicitly supports it as a parameter, otherwise looks good to me. Thanks for adding it!
