actions-eol

Find every dated GitHub Actions removal this repository's workflows will hit and plan the fixes - retiring runner labels (macos-14 removed 2 Nov 2026, ubuntu-22.04 removed 17 Apr 2027) with their brownout windows, ubuntu-latest moving to Ubuntu 26.04, actions still declaring node20 (forced onto Node 24), artifact and cache versions that already fail, set-output, save-state, set-env and add-path, and pull_request_target's default block in public repos - by running actions-eol on the local checkout. Use when the user asks whether GitHub will break their CI, a job failed during a brownout, they saw a "Node.js 20 actions are deprecated" or set-output warning, or they want to bump runner labels and action versions before a deadline.
