Jedrzej Kosinski 7259e664ef Defer record_node_startup_error in prestartup error path; add docstrings ...

Buffer prestartup failures into a module-level list inside main.py
instead of importing 'nodes' (and therefore 'torch') from within the
exception handler. After the normal 'import nodes' line, drain the
buffer via nodes.record_node_startup_error so bootstrap order stays
deterministic regardless of whether a prestartup script succeeded.

Also convert the explanatory '#' comment on the new
/node_startup_errors endpoint into a proper docstring and add a
docstring to execute_prestartup_script, addressing CodeRabbit's
docstring-coverage warning on this PR.

Addresses review feedback on PR #13184.
