feat: add Ollama provider support

Add support for Ollama as a provider in CCS, enabling users to use
local Ollama models (qwen3-coder, gpt-oss:20b, gpt-oss:120b) and
Ollama Cloud models (glm-4.7:cloud, qwen3-coder:480b).

Changes:
- Add base-ollama.settings.json for local Ollama (localhost:11434)
- Add base-ollama-cloud.settings.json for ollama.com cloud API
- Add 'ollama' and 'ollama-cloud' presets to provider-presets.ts
- Update help documentation in api-command.ts and help-command.ts

Usage:
  ccs api create --preset ollama          # Local Ollama
  ccs api create --preset ollama-cloud    # Ollama Cloud
