Move the routing data (schedule->workflows, API dispatch flags, change-detection patterns, passthrough params) into a standalone routing.yml and have compute-workflow-conditions.sh read it, so the scripts hold only the routing logic. collect-params.sh now reads the change patterns from routing.yml, and test-schedule-triggers.js reads the schedule map directly instead of parsing the routing script.

Separates the CircleCI routing data from the routing logic. Stacked on #21579.
A new
.circleci/routing.ymlholds the declarative data:schedules— schedule name → workflowsapi_dispatch— dispatch flag → workflows (includingmain_dispatchandlabeled_pr, whose conditions stay in the script)change_patterns—any/allERE patterns matched against changed filespassthrough_params— params forwarded to continuation configscompute-workflow-conditions.shnow holds only the conditions;collect-params.shreads the change patterns fromrouting.yml; andtest-schedule-triggers.jsreads the schedule map directly instead of regex-parsing the routing script.No routing behavior changes — the same
c-run_*flags are enabled for every trigger/branch/schedule/dispatch case.Test plan
