[Bug] Bash tool output capture fails with false "disk full" (ENOSPC) error on macOS

Bug Description
▎ Bash tool output capture failed with a false "disk full" error: "the temp
▎ filesystem at /private/tmp/claude-501/.../tasks is full (0MB free)" with
▎ ENOSPC. The disk actually had ~1.98TB free (1.2% used). Verified: writes to
▎ the exact path succeeded (5MB test), no APFS snapshots, and the macOS system
▎ log shows zero out-of-space events at that timestamp — so the OS never saw
▎ a real ENOSPC. Looks like a transient glitch in the harness's free-space
▎ check or a race while creating the task output file. One-off occurrence; all
▎ later commands captured output normally. macOS Ventura (Darwin 22.6.0),
▎ APFS, 2TB disk.
