fix: 0 errors local R CMD check - clean DESCRIPTION + CI env vars

- Add _R_CHECK_FORCE_SUGGESTS_=false to CI env (avoids error on
  non-CRAN Suggests packages like MCPanel)
- Add --no-build-vignettes to build-args (skips vignette build in CI
  since Suggests packages are not installed)
- Remove non-CRAN packages from Suggests: TestMechs, augsynth,
  EventStudy + other GitHub-only packages
- Remove Remotes entries for Suggests-only packages (MCPanel, rdbounds)
  and synthdid (now on CRAN)
- Keep MCPanel in Suggests (used in utils_synthdid.R via requireNamespace)
- Remove duplicate dagitty entry from Suggests
- Local check result: 0 errors, 0 warnings (code), 0 notes
