Add Quick mode (nova-lite/Bedrock) as 3rd tier for timeline tool

Timeline now offers Quick/Standard/Deep: nova_lite routes to Amazon
Bedrock nova-lite via LiteLLM (1 credit, ~2s faster), azure_mini stays
gpt-4o-mini (1 credit), azure_full stays gpt-4o (2 credits, Pro only).
ToolModels tier rules: free→nova_lite only, plus→quick/standard,
pro→all three.
