ci: guards → central reusable workflows (comment/leak/identity/doc-links)

Thin callers to freemkv/.github@v1; delete the now-duplicated local ci/ scripts.
Adds concurrency cancel-in-progress and drops the push+PR double-fire (fork PRs
still run). doc-links now resolves toolchain from rust-version (was hardcoded 1.98).
