Extends the existing release-workflow / artifact-hook / labels sections
(from #27 and #39, kept intact) with the remaining adoption guide: the
greenfield bootstrap path, the box/rig/cast conversion checklist, the
exact-tag pinning policy, the portable changelog contributor rule, and
the agent-team-flow adoption checklist with the pin-bump procedure
(docs-sync documented from #19's contract).

The fixture consumer is the workspace root (a uses: step cannot cd);
ceremony rides a subdirectory checkout serving as both the local action
ref and the --source override. CONSUMERS.md gains the wiring, bootstrap,
and pin-bump procedure (#12's section, amended in the same cycle).

Closes#9. .github/workflows/release.yml (workflow_call) replaces box's,
rig's and cast's release.yml: the merge door (facts -> decide -> notes ->
tag+publish+bump, every decision in a tested lib script) and the tag door
(the manual fallback and backfill, no bump). Plus lib/facts.sh (the merge
door's impure half, contract-tested against fixture repos with a stubbed
gh), the self-ref pin guard (.github/scripts/self-ref-check.sh + CI step +
tests), the release-exercise scratch caller (dry wiring), the end-to-end
script-chain rehearsal, and the caller + artifact-hook contracts in
docs/CONSUMERS.md.
