# scripts/run-all-tests.sh — master entrypoint that exercises every check
# stream 11 owns. Designed to be the single command CI invokes.
#
# Stages (each fails fast):
#   1. C++ build + ctest  → scripts/build-cpp-tests.sh
#   2. WASM build          → scripts/build-wasm.sh
#   3. Parity check        → scripts/parity-check.sh
#   4. Lint                → scripts/lint-cpp.sh
#   5. Playground tests    → cd playground && bun run typecheck + bunx playwright test
#
# Flags via env:
#   NISPS_SKIP_PLAYWRIGHT=1   skip the Playwright leg (useful in C++-only loops)
#   NISPS_SKIP_WASM=1         skip WASM build + parity (no emcc available)
#   NISPS_LINT_STRICT=1       treat lint warnings as failures
#
# Exit codes: 0 on full success, otherwise the failing stage's exit code.
