shadowdaoandClaude Sonnet 5.5 b5bb46740d build-push: workflow_dispatch input only to rebuild a single image leg
Gitea cannot re-run one job and a full run takes ~1h. Add a plan job that
turns the optional `only` input (e.g. cac:php85) into one filtered matrix per
image family; image jobs take their matrix from it and are skipped when empty.
Push events / empty input plan the full set as before. Unknown values fail
the plan job. Tests added to multiarch-workflow.test.py.

## plan-legs.sh - decide which image legs of build-push.yaml run.
##
## Env:
## ONLY workflow_dispatch input "only". Empty/blank (and every push
## event) = build everything, exactly as before.
## GITHUB_OUTPUT file the outputs are appended to (set by the runner).
##
## ONLY is a comma list of tokens (spaces ignored):
## cac:php85 cac-fpm:php84 cac-litespeed:php83 cac-lsphp:php82 one leg
## cac | cac-fpm | cac-litespeed | cac-lsphp every PHP version of that image
## shared-httpd | shared-ols that image
## Any other token is an error (exit 2, nothing is written): a typo must fail
## the plan job loudly, never silently build nothing.
##
## Outputs (matrix families = JSON array of phpver, [] = skip the job;
## single-leg images = true|false):
## cac cac_fpm cac_litespeed cac_lsphp shared_httpd shared_ols
