symbiont: pin OGAR git-deps to main (jirak branch absent on github)

Investigation (git fetch + rebase): the local OGAR jirak HEAD 3016c78 is an
ANCESTOR of origin/main (bc21fce, 75 commits ahead) with zero unique commits —
"jirak" was a stale checkout name, never a real OGAR branch, and it does NOT
exist on github. main is a strict superset of the green-build code and is the
canonical resolvable ref. The other three forks (ndarray/ractor/surrealdb) keep
their jirak pins (those branches DO exist on github). The surrealdb [patch]
(keyed on the bare github URL OGAR's workspace uses) still redirects OGAR's
main-pinned surrealdb to our jirak kv-lance source.
