fix(gitops): clean failure display in TUI grid and post-run summary (#236)

Live grid now shows only the project name on failure (no inline error
text), matching the startup checks TUI style.

printSummary renders each failed repo as a multi-line block: the repo
name and elapsed time on the first line, followed by indented dimmed
error lines — making multiline git errors readable instead of broken.

truncateToVisualWidth now appends … when truncating so it is clear
content was cut.
