## What changed
- Coalesce configuration, skill, sandbox, and MCP startup diagnostics into a single summary below the session header, including MCP and sign-in counts.
- Keep the complete warning text in the transcript and update the summary's transcript shortcut when key bindings change.
- Continue rendering warnings that arrive after work begins as inline history entries.
- Hide the MCP startup status row before a turn while preserving the configured interrupt shortcut.
## Testing
- Add coverage for warning ordering and deduplication, transcript details, MCP sign-in counts, resumed sessions, runtime warnings, reflow, backtracking, and interruption without a visible status row.
