tune_specs

<p><code>gsDesignTune()</code> and <code>gsSurvTune()</code> treat most arguments as fixed values.
Wrap an argument in a <code>tune_*()</code> specification to explore candidate values.</p>

Provides systematic, dependency-aware exploration of
group sequential designs created with 'gsDesign'.
Supports reproducible grid and random search over user-defined
candidate sets, parallel evaluation via the 'future' framework,
standardized metric extraction, and auditable reporting for
design-space evaluation and trade-off analysis.
Methods for group sequential design are described in
Anderson (2025) <doi:10.32614/CRAN.package.gsDesign>.
The 'future' framework for parallel processing is described in
Bengtsson (2021) <doi:10.32614/RJ-2021-048>.
