 Implemented frontend Workspace Console tool call grouping. Tool call start/arg/done/result events now project into a single `Call · <tool>` block keyed by call id, with streaming state updates and folded result output. Added generic and TUI-aligned specialized summaries for core tools, including Bash command/output rendering. Validated with frontend check/test, diff check, and Nix package build.

+## Implementation report
+
+Follow-up correction: Read rendering now matches the TUI special case more closely. Consecutive Read calls are aggregated into a single `Call · Read` block, and file contents / tool output are not rendered in the console body. The aggregate lists paths and state only, preserving summaries in detail.
