PSRICalcSM 1.0.0

• Initial CRAN release.
• Core compute_psri_sm() function implementing softmax aggregation of germination components with zero-collapse prevention.
• Modular component functions: compute_msg(), compute_mrg(), compute_cmtg(), compute_rvs().
• softmax_weights() for transparent weight computation.
• calibrate_temperature() for perplexity-based temperature parameter selection.
• Continuous Radicle Vigor Score (RVS, 0-1 scale) replacing the discrete Radicle Vigor Factor used in PSRICalc.
• Synthetic germination_example dataset for demonstrations.
• Companion to PSRICalc (geometric mean method); see package documentation for method comparison and selection guidelines.
