Initial implementation of SwiftDBAI
Chat with any SQLite database using natural language. Built on AnyLanguageModel (HuggingFace) for LLM-agnostic provider support and GRDB for SQLite access. Core features: - Auto schema introspection from sqlite_master (zero config) - NL → SQL generation via any AnyLanguageModel provider - Three rendering modes: text summary, data table, Swift Charts - Drop-in DataChatView (SwiftUI) and headless ChatEngine - Operation allowlist with read-only default - Mutation policy with per-table control - ToolExecutionDelegate for destructive operation confirmation - Multi-turn conversation context - 352 tests across 24 suites, all passing Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
