refactor: rename type interfaces to use I prefix convention
Standardize naming by adding I prefix to all interface types across the codebase (StreamChunk → IStreamChunk, SearchMatch → ISearchMatch, etc.). Also rename conversationStore.ts to ConversationStore.ts for consistency.
Track when conversations are last modified by adding an `updated` field to the Conversation model. Sort conversation history by last updated time instead of creation time for better user experience.
Replace hardcoded color values and custom CSS variables with Obsidian's
built-in theme variables for backgrounds, borders, and interactive elements.
Removes unused isStreaming state and simplifies gradient background. Updates
view display text to "AI Agent".
