- Add reusable TimezoneSelect component with search and UTC offset labels
- Replace plain Select with searchable TimezoneSelect in profile settings,
bot settings, and browser context settings
- Move bot timezone setting from header dialog into bot settings tab
- Resolve timezone with bot > user > system priority for all LLM-facing
time formatting (user message header, system prompt, heartbeat, tools,
memory extraction)
- Format tool output timestamps (history, contacts) in resolved timezone
Move CreateModel, BuildReasoningOptions, ReasoningBudgetTokens and
related types from internal/agent to internal/models as NewSDKChatModel,
SDKModelConfig, etc. This eliminates duplicate ClientType constants and
centralises all Twilight AI SDK instance creation in a single package.
NewSDKEmbeddingModel now accepts a clientType parameter and dispatches
to the native Google embedding provider for google-generative-ai,
instead of always using the OpenAI-compatible endpoint.
