docs: update CLI output examples to match actual console rendering

The output examples in the landing page, getting-started guide, and
README showed stale formatting that didn't match what users actually
see — missing run header, wrong log file line format, and
"iteration(s)" instead of the pluralized form the code produces.

 Watch the output. Each iteration runs the commands, assembles the prompt with the command output, and pipes it to the agent:

 If the agent breaks a test, the next iteration sees the failure output via `{{ commands.tests }}` and fixes it automatically.
