Reconciliation validates the selection and defaults token limits per model. LCore and OGX configuration use model-derived providers, model identifiers, and environment-variable names.

Review comments at @api/v1beta1/openstacklightspeed_types.go:
- Around line 388-391: Update DefaultModel on OpenStackLightspeedCore with a
minimum length of one, and add a CEL validation rule to OpenStackLightspeedCore
requiring lightspeed.defaultModel to match a models[].name; regenerate the CRD
to include these validations.
- Around line 394-405: Add an upgrade path for existing v1beta1 resources whose
former root-level LLM fields leave `spec.models` and
`spec.lightspeed.defaultModel` empty; either migrate those values before typed
reconciliation or document a manual migration that copies them into a named
`models` entry and sets `lightspeed.defaultModel` to that name. Update the
installation guide with the required resource update commands and upgrade order,
ensuring migration occurs before the new CRD schema is applied.

Overall LGTM, thank you!:) I like how the new models configuration looks like.

Allow configuring multiple LLM backends in the CRD by introducing
spec.models[] and spec.lightspeed.defaultModel, replacing the previous
single-model fields. This lets users register multiple model/provider
combinations and explicitly choose a default model for inference
Each configured model now maps to its own OGX provider_id
(provider-<model-alias>) and registers model_id as the alias while
keeping provider_model_id as the upstream model name.
For example, the following configuration:
```
defaultModel: gemini
models:
- name: gemini
llmEndpoint: <redacted>
llmEndpointType: openai
modelName: gemini-3.5-flash
llmCredentials: gemini-secret
- name: gpt-oss
llmEndpoint: <redacted>
llmEndpointType: openai
modelName: openai/gpt-oss-20b
llmCredentials: gpt-oss-secret
```
Will result in two providers called: "provider-gemini" and "provider-gpt-oss";
and models "gemini"and "gpt-oss" (based on the name field).
To specify a model during a query to the /query or /streaming_query the
follow request body can be used, for example:
{"query": "what is rhoso ?", "provider": "provider-gpt-oss", "model":
"gpt-oss"}
If the provider/model is not specified, the default model will be used.
