Backend: code-mode execute now streams per-call progress. Metadata.toolCalls
becomes CallEntry[] ({ tool: dotted-path, status: running|completed|error })
and is published via ctx.metadata on every status change — when a child MCP
call starts and when it resolves/fails — so the tool part updates live.
TUI: add an Execute component (dispatched for the "execute" tool). Condensed
view shows a run header (spinner while running, ✓ when done) plus a live `↳`
line per child tool call, colored on failure; clicking toggles a syntax-
highlighted view of the program source. Unlike Task, there is no child session,
so the call list is sourced entirely from the streamed metadata.
