chore(ci): replace mirror.yml with reusable wrapper

[hyperpolymath]

Summary

Replaces this repo's full mirror.yml (~145 lines, drift-prone) with a thin ~13-line wrapper that calls hyperpolymath/standards/.github/workflows/mirror-reusable.yml@e6b2884722350515934d443daf23442f2195796f (merged via standards#187).

Forge selection (GitLab, Bitbucket, Codeberg, SourceHut, Disroot, Gitea, Radicle) remains gated by Actions vars.<FORGE>_MIRROR_ENABLED exactly as before. secrets: inherit flows the per-forge SSH keys through implicitly.

Why

Estate audit: 289 mirror.yml deployments across the org, 75 unique blob SHAs (76% drift). Drift is action-SHA pin churn, not feature variance — the canonical 7-forge job set is identical across sampled variants. Converging behind the reusable cuts ~94k LOC of estate scaffold and means future changes to mirror logic propagate via one SHA bump.

Part of estate-wide convergence campaign 2026-05-26 (standards#199 / #187).
