### Describe the Bug

`wrangler ai finetune` has no single read or delete command/endpoint for LoRA adapters.

```
Interact with finetune files

COMMANDS
wrangler ai finetune list List your finetune files
wrangler ai finetune create Create finetune and upload assets

GLOBAL FLAGS
-c, --config Path to Wrangler configuration file [string]
--cwd Run as if Wrangler was started in the specified directory instead of the current working directory [string]
-e, --env Environment to use for operations, and for selecting .env and .dev.vars files [string]
--env-file Path to an .env file to load - can be specified multiple times - values from earlier files are overridden by values in later files [array]
-h, --help Show help [boolean]
--install-skills Install Cloudflare skills for detected AI coding agents before running the command [boolean] [default: false]
-v, --version Show version number [boolean
```

I cannot delete any singular LoRA adapter if I choose to not use it, or I cannot retrieve any singular LoRA adapter I have already uploaded. The lack of REST endpoints / wrangler commands available makes development extremely difficult when trying to test out different LoRA adapters. Curious if either is planned.
