Add --keep-duplicates CLI argument to bypass deduplication and forward
to pytest, allowing duplicate test file arguments to be collected
multiple times.
Move RUN_ID assignment from pytest_collect_file to modify_pytest_item.
All File collectors for the same source file share a single run_ids
dict (via RUN_ID_CACHE stash key), so items from duplicate collection
arguments (e.g. with --keep-duplicates) automatically get unique IDs.
Remove CppFile.run_id cached_property — CppTestCase now reads RUN_ID
from its own item stash, which is set during modify_pytest_item.
Fix --repeat option default from string "1" to int 1 — argparse only
applies type= to CLI-parsed values, not defaults.
