fix(dead): exclude working-tree-deleted files from dead scan

When from_disk=True and a file was deleted from the working tree without being committed, _load_file_bytes was falling back to the object store and including the deleted file's bytes in the scan. This caused symbols in deleted files to be incorrectly reported as dead code.

Fix: drop the object-store fallback in from_disk mode. A deleted file has no symbols — none of its symbols can be dead. Simply skip it.

Adds regression test: TestDeadIntegration::test_deleted_working_tree_file_excluded_from_dead_scan

Fixes: muse code dead showing stale symbols for uncommitted file deletions.
