Task: 51289131-5abf-48c3-b553-7e3809c09076 Ollama native adapter.

What changed: internal/ai/llm/ollama implements Provider for POST {base}/api/chat (stream false, schema in format, temperature in options) and GET {base}/api/tags. No auth header. Unreachable host names the base. Model-not-found names the model. Redirects are not followed.

Done-condition: httptest contract tests cover success, schema output, model missing, and unreachable host. Developer reports gofmt, go vet, go test -race, and CGO_ENABLED=0 go build passed.

Base: feature/5dd6e253-cc9b-41f3-9091-bb834f7a373a-llm-provider-layer at 15886f2c55.

internal/ai/llm/ollama implements llm.Provider over plain net/http:
POST {base}/api/chat with "stream": false, the request schema in
"format", and options.temperature / options.num_predict only when the
request sets them; GET {base}/api/tags for ListModels and Verify. No
Authorization header is sent and redirects are not followed.

Usage comes from prompt_eval_count/eval_count. A schema reply that is
not a JSON object is ErrBadOutput. HTTP 404 on /api/chat is an
ErrProvider naming the configured model, without quoting the body.
Refused connections and timeouts match ErrTimeout and say
"Ollama not reachable at {base}"; a cancelled context stays
context.Canceled. The base URL is required, absolute http or https
(LAN hosts allowed), and may not carry userinfo, a query or a fragment.

Contract tests replay sanitized fixtures adapted from Ollama's public
API docs against httptest servers: success, schema output, model
missing and unreachable host.

Ollama: only treat a 404 as model-not-found when the body says so

A 404 from a proxy without /api/chat, or any other 404 error, was
reported as the configured model being missing. Generate now checks the
{"error": ...} payload for Ollama's model-not-found message naming the
configured model (double- or single-quoted); any other 404 stays a
ProviderError with its redacted body excerpt.
