feat(agents-vault): sync the vault from the claude and agy wrappers

Both wrappers stay behind the C1 guard, so disabling
__fish_config_op_aliases still passes straight through to the real binary.

Launch commits but never pushes, keeping the network and any credential
prompt off the critical path; pushing is left to the Claude Code SessionEnd
hook. agy has no such hook, so its memory lands one launch later.
