chore(agents): fix bug-hunt-pool-supervisor tracking prefix AUTO-BUG-POOL → AUTO-BUG-SUP

Approved proposal: #7875
Pattern: workflow_fix (incomplete previous fix)
Evidence: PR #7586 received REQUEST_CHANGES (review #4786) identifying that
the fix was incomplete. 8 AUTO-BUG-POOL references remain in master branch
after PR #7586 was never merged. The watchdog and other agents expect
AUTO-BUG-SUP. Current tracking issue #7884 uses [AUTO-BUG-POOL] prefix.
Fix: Complete search-and-replace of all 8 AUTO-BUG-POOL occurrences to
AUTO-BUG-SUP, and Bug Detection Report → Bug Hunt Status throughout.

ISSUES CLOSED: #7875
