don't require pulling stubs for cloud models (#14574)

* don't require pulling stubs for cloud models

This is a first in a series of PRs that will better integrate Ollama's
cloud into the API and CLI. Previously we used to have a layer of
indirection where you'd first have to pull a "stub" model that contains
a reference to a cloud model. With this change, you don't have to pull
first, you can just use a cloud model in various routes like `/api/chat`
and `/api/show`. This change respects
<https://github.com/ollama/ollama/pull/14221>, so if cloud is disabled,
these models won't be accessible.

There's also a new, simpler pass-through proxy that doesn't convert the
requests ahead of hitting the cloud models, which they themselves
already support various formats (e.g., `v1/chat/completions` or Open
Responses, etc.). This will help prevent issues caused by double
converting (e.g., `v1/chat/completions` converted to `api/chat` on the
client, then calling cloud and converting back to a
`v1/chat/completions` response instead of the cloud model handling the
original `v1/chat/completions` request first).

There's now a notion of "source tags", which can be mixed with existing
tags. So instead of having different formats like`gpt-oss:20b-cloud` vs.
`kimi-k2.5:cloud` (`-cloud` suffix vs. `:cloud`), you can now specify
cloud by simply appending `:cloud`. This PR doesn't change model
resolution yet, but sets us up to allow for things like omitting the
non-source tag, which would make something like `ollama run
gpt-oss:cloud` work the same way that `ollama run gpt-oss` already works
today.

More detailed changes:

- Added a shared model selector parser in `types/modelselector`:
  - supports `:cloud` and `:local`
  - accepts source tags in any position
  - supports legacy `:<tag>-cloud`
  - rejects conflicting source tags
- Integrated selector handling across server inference/show routes:
  - `GenerateHandler`, `ChatHandler`, `EmbedHandler`,
    `EmbeddingsHandler`, `ShowHandler`
- Added explicit-cloud passthrough proxy for ollama.com:
  - same-endpoint forwarding for `/api/*`, `/v1/*`, and `/v1/messages`
  - normalizes `model` (and `name` for `/api/show`) before forwarding
  - forwards request headers except hop-by-hop/proxy-managed headers
  - uses bounded response-header timeout
  - handles auth failures in a friendly way
- Preserved cloud-disable behavior (`OLLAMA_NO_CLOUD`)
- Updated create flow to support `FROM ...:cloud` model sources (though
  this flow uses the legacy proxy still, supporting Modelfile overrides
  is more complicated with the direct proxy approach)
- Updated CLI/TUI/config cloud detection to use shared selector logic
- Updated CLI preflight behavior so explicit cloud requests do not
  auto-pull local stubs

What's next?

- Cloud discovery/listing and cache-backed `ollama ls` / `/api/tags`
- Modelfile overlay support for virtual cloud models on OpenAI/Anthropic
  request families
- Recommender/default-selection behavior for ambiguous model families
- Fully remove the legacy flow

Fixes: https://github.com/ollama/ollama/issues/13801

* consolidate pull logic into confirmAndPull helper

pullIfNeeded and ShowOrPull shared identical confirm-and-pull logic.
Extract confirmAndPull to eliminate the duplication.

* skip local existence checks for cloud models

ModelExists and the TUI's modelExists both check the local model list,
which causes cloud models to appear missing. Return true early for
explicit cloud models so the TUI displays them beside the integration
name and skips re-prompting the model picker on relaunch.

* support optionally pulling stubs for newly-style names

We now normalize names like `<family>:<size>:cloud` into legacy-style
names like `<family>:<size>-cloud` for pulling and deleting (this also
supports stripping `:local`). Support for pulling cloud models is
temporary, once we integrate properly into `/api/tags` we won't need
this anymore.

* Fix server alias syncing

* Update cmd/cmd.go
