Protects against 'unbound variable' errors even if set -u is
re-enabled or inherited. Every [[ -n "$UPPER_VAR" ]] pattern now
uses [[ -n "${UPPER_VAR:-}" ]] to safely default to empty.

The autonomous refactoring added `set -euo pipefail` but the scripts
check optional env vars with `[[ -n "$VAR" ]]` which is a fatal error
under nounset when the var isn't set (e.g. SPRITE_NAME, OPENROUTER_API_KEY).
Fix: downgrade to `set -eo pipefail` across all 42 affected files.

When scripts run via `bash <(curl ...)`, BASH_SOURCE resolves to
/dev/fd/N, making the relative path `../../shared/common.sh` fail.
Fix: add remote fallback — try local file first, fall back to
fetching shared/common.sh from GitHub via eval+curl.
Applied to all 5 refactored lib/common.sh files (sprite, hetzner,
digitalocean, vultr, linode).

Three issues broke the OAuth callback server on macOS:
1. echo -e doesn't work in bash 3.x — \r\n appears as literal text
in the HTTP response, browser gets malformed headers.
Fix: pre-write response with printf to a file before the subshell.
2. local variables inside ( ... ) & subshell — undefined behavior in
bash 3.x since subshells aren't function scope.
Fix: use plain variables in subshells.
3. ((elapsed++)) when elapsed=0 evaluates to falsy — set -e kills
the script on the first iteration of the timeout loop.
Fix: use elapsed=$((elapsed + 1)) instead.
Also simplified nc_listen detection to only check for BusyBox
(the -p flag check could misfire on macOS nc).
Applied to all 10 lib/common.sh files.
