fix: port conventional-commit version bump from metriccalc

[monazhu]

Ports the working CI setup from c3d-metriccalc (DS-980 / DS-981) so R-package version management is consistent across our R repos.

Changes

version-bump.yaml — replaces the manual workflow_dispatch bump, which pushed directly to protected main and failed every run (version has been stuck at 0.1.0):

• Bump type derived from conventional commits on push to main (feat!:/BREAKING CHANGE → major, feat: → minor, fix:/perf:/refactor: → patch).
• Opens a chore/bump-version-* PR and enables auto-merge (merge commit, never squash) — main requires one approving review from a project member since this repo is public, so the bump PR lands once someone approves.
• Force-pushes the bump branch and skips PR creation if one is already open, so failed runs don't wedge it.
• New tag job: once the bump PR's merge commit lands on main, tags v<version> (preserves the old workflow's tagging behavior).

R-CMD-check.yaml — deduped to match metriccalc:

• pull_request-only trigger (every change reaches main through a PR, so the push trigger double-ran checks).
• Skips chore/bump-version-* PRs — they only touch the DESCRIPTION version string.

Deployment notes

• Reuses the VERSION_BUMP_TOKEN secret, updated to the fine-grained PAT used by metriccalc (needs Contents R/W + Pull requests R/W and repo access to this repo).
• Repo settings: allow_auto_merge and delete_branch_on_merge enabled alongside this PR.

Pull request overview

Ports a CI-driven version-bump workflow (based on conventional commits) to keep the R package DESCRIPTION version and release tags consistent across R repositories, and aligns the R CMD check workflow triggers with that flow.

Changes:

• Replaces the manual version bump dispatch with an automatic bump PR flow on pushes to main, deriving bump type from conventional commit messages.
• Adds an automated tagging job intended to tag v<version> once the bump PR merge commit lands on main.
• Adjusts R-CMD-check to run only on pull_request and skip version-bump PRs.

• git ls-remote patterns match full ref names (e.g., refs/tags/v1.2.3). Using just v${VERSION} will not reliably detect an existing tag, so re-runs may try to recreate an existing tag and fail on push.

          if ! git ls-remote --exit-code --tags origin "v${VERSION}" >/dev/null; then
