## What changed


- **Fullscreen transcript search**: Ctrl+Shift+F, incremental match highlighting, configurable theme colors, next/previous navigation.
- **Configurable default tools**: `defaultTools` setting for initial built-in tool selection globally or per project.
- **Fullscreen exit output**: choose between printing final transcript or only a resume hint.
- **Experimental strict JSON sampling**: `PI_EXPERIMENTAL=1` enables constrained sampling for read, bash, edit, write.
- **--use-theme flag**: choose initial per-run interactive theme without changing saved settings.
- **Extension API**: `pi.sendUserMessage()` gains `expandPromptTemplates` for dispatching commands and expanding skills/templates.
- **Cloudflare AI Gateway**: `createGatewayBindingFetch()` for routing through Workers AI binding without API token.
- **OpenAI Codex diagnostics**: `endTurn` signal preserved in AssistantMessage.
- **Mistral SDK replaced**: native Chat Completions HTTP stream, eliminating generated client and schema runtime overhead.
- **Kimi Coding**: uses pi's runtime User-Agent header.
- **Fixes**: managed-tool downloads no longer delay TUI startup; model selector opening no longer cancels catalog refresh; GitHub Copilot login rate-limited concurrency; fullscreen search snap-back and mouse input leaks fixed; LaTeX argument parsing; transitive nanoid CVE; extension tool result fallback rendering; JSON/RPC message_update cumulative usage; sendMessage triggerTurn=false fix; defaultTools dropping extension tools; subagent example YAML and config inheritance fixes; custom system prompt concatenation fix.
