P0 has no external deps, so go.sum doesn't exist yet and
`git diff --exit-code go.mod go.sum` errored (exit 128) on the missing
path. Use `git status --porcelain` so the check survives a not-yet-created
go.sum and still catches an untidy go.mod or a newly-created go.sum.

Batteries-included agent-harness base, extracted from mort's agent layer.
This first cut establishes the module + the zero-coupling core primitives:
- lane, dispatchguard, pendingattach, run/progress.go: moved verbatim from mort
- config: host config Source seam + env-var default (nil-safe helpers)
- deliver: output-egress seam + Discard/Stdout defaults
- identity: AdminPolicy + MemberResolver seams (nil-safe)
- fanout: programmatic N×M swarm (bounded global + per-key concurrency)
- README/CLAUDE.md with the vibe-coded banner; CI with Go gates +
the "core stays majordomo+stdlib only" invariant
Core builds with stdlib only today; majordomo enters at P1 (model/structured).
go build/vet/test -race all green.
