Merge main into cran-submission

Same three-way conflict as the previous main → cran-submission merge:

* DESCRIPTION — kept the 0.1.0 release Title and version from
  cran-submission. Main's dev version (0.0.0.9054 after #218) is
  superseded.
* NEWS.md — kept cran-submission's "first CRAN release" intro and
  0.1.0 structure. All of main's incoming dev-version bullets
  (#218 R toolchain + gh issue allowlist, findjags casing,
  #210/#216/#217, OS-snapshot consolidation, Copilot decomposition)
  are already represented under ## Developer-facing changes from
  the prior merge and the "Incorporate PR #218 changes" cherry,
  so the main-side block is dropped rather than re-merged.
* inst/WORDLIST — union of both branches, ASCII-sorted, CRLF
  preserved.

Workflow files (.github/workflows/{claude,copilot-setup-steps,
test-coverage}.yml) auto-merged to main's version, so cran-submission
now inherits #218's @claude R toolchain, gh issue allowlist, and
the lowercase runjags::findjags() consistency fix in test-coverage
and copilot-setup.
