#
# Downloads the prebuilt `neurosploit` binary + agent library, installs them, and
# sets up PATH + NEUROSPLOIT_BASE so you can run `neurosploit` from ANY folder —
# no need to cd into the repo. Falls back to building from source if no prebuilt
# asset fits (or NEUROSPLOIT_BUILD=1). Safe to re-run (idempotent). Honors:
#   NEUROSPLOIT_DIR   install dir         (default: ~/.neurosploit-app)
#   NEUROSPLOIT_REF   release tag/branch  (default: latest release)
#   NEUROSPLOIT_BUILD 1 = build from source instead of downloading
#   PREFIX            bin symlink dir     (default: ~/.local/bin)
