esp_reactor_is_pointer_width row: its grep matched the B in "PXXDBG"

Found 2026-10-19 in the full row sweep. grep -o '[0-9]*B' over the line PXXDBG a.datamap bss 2920B reactors printed B (zero digits, from "PXXDBG") as well as 2920B, so expect_same saw two lines and failed while the value was right. The row was added in 68f3931050 (2026-10-09), after the recipe had already started stopping at row 593, so it never ran green.

Fix: grep -o '[0-9][0-9]*B'.
