Subject: [PATCH] feat(snowflake-cortex): add Snowflake Cortex provider

Adds the snowflake-cortex provider which exposes Snowflake's Cortex
REST API (OpenAI Chat Completions-compatible endpoint) to opencode.

Provider details:
- npm: @ai-sdk/openai-compatible
- API: https://${SNOWFLAKE_ACCOUNT}.snowflakecomputing.com/api/v2/cortex/v1
- Auth: SNOWFLAKE_ACCOUNT + SNOWFLAKE_CORTEX_PAT (Programmatic Access Token)

Models (11, all with tool_call support):
- Anthropic: claude-opus-4-7 (beta/preview), claude-sonnet-4-6,
  claude-sonnet-4-5, claude-haiku-4-5
- OpenAI: openai-gpt-5.4 (beta), openai-gpt-5.2, openai-gpt-5.1,
  openai-gpt-5 (beta), openai-gpt-5-mini (beta), openai-gpt-5-nano (beta),
  openai-gpt-4.1

Models without tool_call support (deepseek-r1, llama3.1-70b,
snowflake-llama-3.3-70b, mistral-large2) are excluded per Snowflake docs:
"Tool calling is supported for OpenAI and Claude models only."

Preview/not-GA models are marked with status = "beta".

Cost fields are intentionally omitted on all models. The Cortex REST API
is billed in USD (AI_INFERENCE service type) at rates defined in the
Snowflake Service Consumption Table.

Closes #1895
