fix(ci): use --ignore flags instead of marker filtering

Replace pytest -m marker filtering with explicit --ignore flags for
external_deps tests. This is more reliable in CI environments where
addopts parsing can behave differently.

Ignored test files/dirs:
- tests/integration/
- tests/e2e/
- tests/benchmarks/
- Individual unit tests with external_deps marker
