fix(workforce): a crew should not read as an alphabetical run

Seeding the name pick with the role index (0..n) started every crew at the top
of the pool and took the next free names, so the first mission after the switch
to per-mission crews hired Aarav, Abebe, Adaora, Adrian, Agnieszka. Unique and
correct, and transparently generated.

Seed from the claw's own uuid instead. UUIDv7 puts its random bytes LAST — the
leading bytes are a timestamp, which would cluster the same way — so the tail
is what spreads five picks across the whole pool.
