Fix GH#96: remove undeclared Try::Tiny dep, add non-blocking blead CI (#98)

* Remove undeclared Try::Tiny dependency from t/diag.t

t/diag.t used Try::Tiny but it was never declared as a test
prerequisite. On a freshly built perl that does not already have
Try::Tiny installed (e.g. blead 5.45.1, as reported via IRC by @Tux),
the toolchain does not pull it in, so t/diag.t dies at compile time
("Can't locate Try/Tiny.pm") and `make test` fails -- making the
distribution appear not to install (GH#96).

The two try{} blocks only swallowed exceptions around diagnostic
Net::SSLeay version calls, so a plain eval { ...; 1 } or diag(...) is
equivalent. This drops the dependency entirely instead of adding it to
the prereqs, which keeps the test suite installable on minimal perls.

* CI: test on Perl blead (devel), non-blocking

Add a container-based job using perldocker/perl-tester:devel (which
tracks the latest Perl development release) so we get an early signal
when the dist breaks on the upcoming Perl -- exactly the class of
problem behind GH#96, which the stable CI matrix (topping out at 5.42)
never exercised.

The job deliberately has no continue-on-error: a failure shows up as a
red X so it is visible. Keep it OUT of the required status checks in
branch protection so blead breakage never blocks a merge -- we want the
signal, not a gate.
