Cross-check test deletions against the regression ledger

Before deleting tests that appear shallow or redundant, cross-check every candidate against the project’s historical regression ledger or caught-bug record. A narrowly shaped test may be the only durable guard for a real failure that browser coverage cannot reproduce safely or cheaply. Restore or retain any candidate tied to a confirmed regression unless an equivalent end-to-end check covers the same boundary. This adds a small audit step but prevents cleanup heuristics from erasing institutional memory.
