fix(pr-watch-test): run_case_capture in parent shell, not subshell

Browse Source 
The run_case_capture helper was being called in command substitution
(out=$(run_case_capture ...)), which runs it in a subshell. This caused
the ok/bad updates to the pass/fail counters to be discarded.

Fix by having the helper write output to a caller-provided file parameter,
then reading from that file in the caller. This keeps the helper in the
parent shell where counter updates are preserved.

Addresses Codex P2 review on commit ec30c8a7.
