-- Store model-dependent generation and runtime preferences per model and

-- Replace the default system prompt with a concise coding-agent prompt and edit

-- Add the selected project's `AGENTS.md` to the initial prompt when the first

-- Order ordinary sessions by most recent use while keeping pinned and archived
-  sections intact. (#31)
-- Confirm every session deletion path before deleting metadata and its KV
-  checkpoint. (#32)
-- Keep chat pinned to the end only while the user is already there; append new
-  streamed content without fighting manual scrolling and remove the current
