rootWishartHD 0.95.1

• CRAN-safe multiprecision default: builds now use Boost cpp_dec_float from BH with DW_USE_MPFR=0; local source builds can opt in to MPFR/GMP with DW_USE_MPFR=1.
• Added rootWishartHD_mpfr_enabled() and runtime warnings when the deprecated MPFR-specific interface is requested but MPFR was not compiled.
• Renamed the main user-facing workhorse functions to remove experimental from the public API: doubleWishart_log(), doubleWishart_scaled(), singleWishart_log(), and singleWishart_cdf().
• Renamed the global runtime option to options(rootWishartHD.force_multiprecision = TRUE).
• Activated tinytest via tests/tinytest.R and kept long numerical sweeps under inst/validation/ for manual release validation.
• Reduced vignette Monte Carlo examples and kept multi-core benchmark code in non-evaluated chunks.
• Hardened theta-scale validation, large-s routing, p-value/critical-value fallbacks, and single-Wishart input validation.
