Move volatile current time and middle-pane data out of the system prompt and into a hidden userMessageContext stored on each user message. Reconstruct the LLM-facing message from this persisted context so older conversation turns remain stable across later requests while UI-facing content stays unchanged.
Keep finite branch instructions such as voice, search, code mode, agent notes, and workdir behavior in the system prompt so each conversation can still benefit from reusable prompt-cache prefixes.
Cmd+K (Ctrl+K on Win/Linux) now opens a unified palette with two
modes: Chat (default) and Search (existing behavior). Tab cycles
between them. In Chat mode, if the user triggered the shortcut from
the markdown editor, the palette auto-attaches a removable chip
showing the note path and precise cursor line. Enter sends the
prompt to the right-sidebar copilot — opening the sidebar if closed
and starting a fresh chat tab — with the chip carried as a
FileMention whose lineNumber is forwarded to the agent as
"... at <path> (line N)" so the agent can use workspace-readFile
with offset to fetch the right slice on demand.
Line numbers are computed against the same getMarkdownWithBlankLines
serializer used to write notes to disk, so the reference is
byte-identical to what the agent reads back.
