hostname, username, and the other unprefixed names collide with shell
and system variables (fish makes hostname read-only, Windows already
defines USERNAME). The generator now reads LIVESYNC_HOST, LIVESYNC_USER,
LIVESYNC_PASS, LIVESYNC_DB, and LIVESYNC_PASSPHRASE first and falls back
to the old names, so existing instructions keep working.
