fix(bash): glob pattern matching in [[ == ]] and [[ != ]] (#244)

## Summary
- `[[ ]]` conditional now uses glob matching (*, ?, [...]) for `==` and
`!=` operators
- Previously did exact string comparison, causing `[[ "hello.txt" ==
*.txt ]]` to fail
- Leverages existing `pattern_matches()` method

## Test plan
- [x] 7 new tests: star, question, prefix, suffix, negation, no-match,
exact
- [x] `cargo test --all-features` passes
- [x] `cargo clippy` and `cargo fmt` clean
