Extract SQLiteDataStore into separate file

[Copilot]

Separates SQLite data storage from SQL query generation logic for improved modularity.

Changes

• Created src/analysis/sqlite.ts - contains SQLiteDataStore class with all database operations (loadData, query, getSchema, close)
• Updated src/analysis/sql.ts - now contains only generateSQL() LLM function, removed SQLiteDataStore class
• Updated src/analysis/index.ts - exports SQLiteDataStore from new file, maintains backward compatibility

File Structure

src/analysis/
├── sqlite.ts     // Database wrapper (new)
├── sql.ts        // LLM SQL generation
├── code.ts       // Code execution
└── index.ts      // Re-exports

All existing imports continue to work through src/analysis/index.ts.

Original prompt

Extract the SQLiteDataStore class into its own file for better code organization and clarity.
