E7: find the Aside CLI in ~/.local/bin when it is not on PATH (#2902)

The installer puts aside in ~/.local/bin, which is not on the default macOS
login PATH, so the probe said NEEDS_ASIDE ('download Aside') for a healthy
install. The probe now falls back to ~/.local/bin/aside, drives the resolved
binary, and prints READY: <path> when it is off PATH so later blocks run that
path. Ported from PR #2965 onto the current _gs_d probe.
