Changes in version 1.0.0                        

Initial Public Release

  - Core mixture model implementations: MPCA (Mixture of Probabilistic
    Component Analyzers) and MFA (Mixture of Factor Analyzers)
  - EM algorithm implementations in C++ via Rcpp/RcppArmadillo for
    performance
  - Soft EM with responsibility-weighted updates
  - K-means based initialization for cluster assignments
  - Comprehensive model selection tools:
      - BIC-based grid search over (K, r)
      - ICL (Integrated Complete-data Likelihood) with temperature
        parameter
      - Cross-Validation with 1-SE rule
      - Bootstrap stability selection for K
      - Two-stage selection for stability
  - r-selection framework: global, clusterwise, and hybrid modes
  - Rotation and flip utilities for synergy alignment
  - Complete EMG preprocessing pipeline (DC removal, bandpass, notch,
    rectification, envelope, normalization)
  - Visualization functions for muscle synergy analysis with unified
    ggplot2 theme
  - Simulation utilities for generating mixture data with optional AR(1)
    temporal noise
  - HPC parallel computation support via future/PBS
  - Comprehensive testing infrastructure with testthat
  - Quickstart vignette and package documentation
