fix: remove pragma no cover from covered lines

ROOT CAUSE:
strict-no-cover check failed because pragma comments were on lines that ARE
covered by tests:
- __repr__ method is tested by test_depends_repr
- Defensive check at line 128 is covered by dependency tests

CHANGES:
- Removed # pragma: no cover from Depends.__repr__() method
- Removed # pragma: no cover from defensive if dep_name in deps check

IMPACT:
- Fixes strict-no-cover CI failure
- All code remains properly tested
- pragma comments only used where appropriate

Refs: #2081
