Reclaim disk on a workspace Mac

T3 Code threads run on both Macs; Jorge picks the host from his phone. <clone>/.host says which one you are on (mini or laptop). The script is the same on both, and paths are derived, never machine-specific. Three numbers for the internal /System/Volumes/Data, each overridable by env: target 90 GiB (STORAGE_HYGIENE_TARGET_GIB, only labels the run), Telegram warning 75 (STORAGE_HYGIENE_ALERT_GIB, scheduled job only) and pressure 40 (STORAGE_HYGIENE_PRESSURE_GIB, the only number that shortens gates).
