Introduce support for a new 'pi' agent across client and server. Client: add Pi icon, include a built-in Pi command preset, extend settings validation/types, bump settings storage version and add migration to ensure built-in presets are present. Server: accept 'pi' in agent_type CHECKs, add migratePiAgentType to recreate agent_sessions with updated constraint, update agent detection and log discovery to recognize Pi paths and session IDs. Tests: update multiple tests to set up PI_HOME and expect the new built-in preset. Overall changes add end-to-end recognition and persistence for the Pi agent type.
Detect and extract user messages from Pi's TUI which uses an RGB background color for user input. Adds extractPiUserMessagesFromAnsi to parse ANSI scrollback for the 48;2;52;53;65 background pattern, and getTerminalScrollbackWithAnsi to capture tmux content with ANSI escape codes preserved. The main matching flow now falls back to Pi detection when no Claude/Codex messages are found. Unit tests for Pi extraction were added, and an integration test timeout was increased to 10s to reduce flakiness.
