Add an AI client module that integrates with OpenAI-compatible API providers (OpenAI, Perplexity, and custom endpoints) to provide AI-assisted chat within CProof. Users can start sessions with /ai start, send prompts, receive responses in a dedicated AI window, switch between providers and models, and manage API keys — all with tab-completion. Providers are configured via /ai set commands with per-provider API keys, endpoints, default models, and custom settings. Two default providers (openai, perplexity) are seeded on first use. Provider state persists in [ai/<name>] sections of the preferences keyfile with automatic migration from the previous flat-key format. The /ai command integrates into the existing command system with 8 subcommands covering provider management, session lifecycle, model fetching, and conversation clearing. Autocomplete uses the standard flat prefix-matching chain for reliable tab-completion at every nesting level. A new ProfAiWin window type is added to the window system. Architecture: Async design: HTTP requests run on a background thread (pthread) to avoid blocking the ncurses UI loop; results are displayed on the main thread via direct function calls Thread safety: AIProvider and AISession use atomic ref-counting and mutex-protected session state; the request thread snapshots all session data before making the HTTP call Window validation: wins_ai_exists() prevents use-after-free when the user closes the AI window during an in-flight HTTP request (~60s) Privacy: store:false is sent with every request to prevent providers from persisting conversations or using them for training Response size limit: 10MB cap with immediate curl abort via CURL_WRITEFUNC_ERROR to prevent OOM JSON parsing uses unified helpers for both chat responses and error envelopes with consistent escape decoding. The response parser tries Perplexity /v1/responses "text" field first, then falls back to OpenAI "content". Error parsing extracts provider error.message from the standard envelope format. Model parsing handles multiple API response formats (OpenAI list, Perplexity, array) including edge cases. Tests include 470+ lines of unit tests covering provider management, session lifecycle, JSON parsing (multiple formats), autocomplete cycling, and error handling, plus functional tests for /ai command dispatch. A stub_ai.c module isolates unit tests from UI dependencies.
