- .wiki/Coding-Standards.md: fix PHPDoc bullet wording (add missing preposition)
- build.sh: add set -euo pipefail for strict error handling
- build.sh: fix SC2115 (use ${var:?} to prevent rm -rf /)
- build.sh: fix SC2164 (cd build || exit 1)
- build.sh: fix SC2028 (use printf instead of echo for escape sequences)
- build.sh: fix SC2035 (use ./*.php glob to avoid dash-named files)
