feat(missions): commit as the operator, overridable per deployment
Delivery commits now carry "Omar Sobh <[email protected]>" by default, so
pushed branches associate with the operator's forge account the way their
own commits do. CLAWMATES_COMMIT_NAME / CLAWMATES_COMMIT_EMAIL override
it — a shared instance wants a bot identity, not a person's.

This is attribution, not the fix. What made 019fc450's phase fail was the
*absence* of any identity: the server container has none of its own, so
git commit exits 128 regardless of which name would have been used. That
was fixed in 25d9805; this only changes the value. The push credential is
GITEA_TOKEN throughout and is untouched by any of it.

Since the author line now names a person, the commit body says plainly
that agents authored the work — otherwise autonomous commits would be
indistinguishable from hand-written ones in git log. Also fixes 13 stray
spaces that a string continuation had baked into every message body.
