## [Unreleased]

### Added

- **`/perplexity-config` command** — Interactive configuration for default model and incognito mode, stored at `~/.config/pi-perplexity/config.json`
- **Model selection** — New `model` parameter on `perplexity_search` tool to choose Perplexity backend model (Sonar, GPT-5.4, Claude 4.6 Sonnet Thinking, Gemini 3.1 Pro, Deep Research, etc.)
- **Incognito toggle** — New `incognito` parameter to control whether searches appear in Perplexity web history
- **Config priority chain** — Per-call params → env vars (`PI_PERPLEXITY_MODEL`, `PI_PERPLEXITY_INCOGNITO`) → config file → defaults
- **Config display in TUI** — Render components now show model and incognito status
