Subject: [PATCH 1/2] fix: gracefully skip unreadable .env in Boot::loadDotEnv

Test ResponseSendTest::testHeaderOverride fails when tests run in random
order because the spawned process (#[RunInSeparateProcess]) calls
Boot::loadDotEnv() -> DotEnv::parse(), which throws InvalidArgument-
Exception when .env exists but is unreadable. The fix catches the
exception in loadDotEnv() so .env errors are silently ignored - .env
is optional.

Subject: [PATCH 2/2] fix: isolate test bootstrap from project .env file

Set $paths->envDirectory to TESTPATH in the test bootstrap so that
separate-process tests (#[RunInSeparateProcess]) look for .env in a
controlled directory instead of the project root. This prevents crashes
when a parallel test creates or modifies .env at the project root.
