test(bootstrap): port the remaining env setup from tests/bootstrap.php

Add NO_COLOR=1, the COMPOSER/COMPOSER_VENDOR_DIR/COMPOSER_BIN_DIR clears and
the timezone normalization, and make bootstrap() Once-guarded so additional
call sites stay safe. Wiring it into every test binary still needs a libtest
setup hook (ctor crate or fixture-level calls), recorded in the TODO.
