Refactor daemonize to improve process safety

- Removed `ensure_pressed(hmmfile)` from `daemonize()` function.
- Added `ensure_pressed(hmmfile)` to `spawn()` function.
- Incremented version from 0.16.3 to 0.16.4 in `pyproject.toml`.

The `ensure_pressed` step is necessary before `spawn()` to verify the
integrity of `hmmfile`, ensuring robust daemon initialization. Additionally,
this avoids redundancy in the `daemonize()` method. Updated version
number for release tracking and to reflect change.
