fix: track quarantine/deadcode in git so contributors see quarantined symbols

The quarantine/ directory was gitignored, hiding 38 dead-code files
from other contributors. These are symbols identified by
TestNoDeadExports and moved out of active code with .dead extension.
Contributors need visibility into what was quarantined to decide
whether to delete permanently or resurrect.
