klct v0.1.0

• This is the first functional release of klct, containing the ability to
  analyze NeoScan microCT data comparing two treatment groups.
• Sites analyzed include femoral metaphysis (trabecular and cortical), femoral
  diaphysis (cortical), and lumbar vertebra (trabecular).
• Supports both parametric and nonparametric statistical tests via the test
  parameter ("parametric" or "nonparametric"):
  • Two-treatment comparisons (compare_groups()): Student's t-test or
    Wilcoxon rank-sum test.
  • Two-way Treatment × Sex comparisons (compare_groups_2x2()): two-way
    ANOVA or Aligned Rank Transform via ARTool::art().
• Dynamic measure detection: detect_trabecular_measures() matches ^Tb.
  columns; detect_cortical_measures() captures all other numeric non-metadata
  columns. A shared internal helper .resolve_measures() centralizes measure
  resolution across all analysis and plotting functions.
• The measures parameter (available in compare_groups(),
  compare_groups_2x2(), and plot_groups()) accepts NULL for sensible
  defaults, "all" for all detected columns, or a custom character vector.
  default_trabecular_measures and default_cortical_measures are exported.
• Omnibus tables in two-way results are trimmed to Factor, P, and Sig
  columns only.
• Pairwise comparisons are merged directly into the Group Summaries table
  (blank for the first group, p-value and significance stars for the second
  group within each sex), matching the compare_groups() convention. The table
  heading reflects the test used (t-test or Wilcoxon).
• Includes four R Markdown templates:
  • "Compare Two Treatments" for analyzing each sex separately.
  • "Compare Two Treatments (Mayo)" — Mayo-themed version using
    mayodown::mayohtml.
  • "Compare Two Treatments and Two Sexes" for a full two-way design.
  • "Compare Two Treatments and Two Sexes (Mayo)" — Mayo-themed version
    using mayodown::mayohtml.
• Template features:
  • Parametric and nonparametric results are displayed as separate tabs.
  • By-sex plot tabs are consolidated into a single tab (differing only in
    significance annotations).
  • Combined Sexes Plots tabs are included in all sections.
  • All templates accept a test parameter in the YAML header.
• Mayo-themed templates use the mayodown package for consistent branding,
  including the Mayo logo, color scheme, and copyright footer.
• The color-text.lua Pandoc filter is provided by mayodown, enabling
  colored significance annotations in all template formats.
