Handle invalid formatter options when printing styles - #3315

pygmentize -S default -f html -O linenostart=invalid currently treats a bad formatter option as an unhandled highlighting error; adding -v raises the exception.

Handle OptionError when constructing the formatter for -S, as the normal highlighting path already does. Invalid options now print the actionable error and return exit code 1. Regression tests cover both normal and verbose mode.

Validation: uv tool run tox -e py passed (5332 tests, 16 skipped). Both new cases failed before the fix. Ruff 0.15.2 and git diff --check passed.
