smrt-contribute

Use when working in a fork or clone of the happyvertical/smrt repository as an outside contributor, for example "fix a bug in smrt-jobs and open a PR", "contribute this change upstream", or "add docs to smrt-core". Gives the fork pull-request procedure from CONTRIBUTING.md and the traps that fail from outside (package-name test filters, format then lint, generated knowledge pages, PR title length, no changesets, fork CI approval). Do not use in a project that merely depends on smrt packages (use smrt-catalog), or in a maintainer session where the control-plane skills (implement, claim-issue, review-cycle, ship) are installed.
