sync_agent() now returns bool (false if any step fails). ensure_all()
collects the names of agents whose sync failed and raises a single
set_boot_warning with the aggregated list:
forge: per-agent sync failed for: alice, bob (see journal for per-step
detail)
The static_kind() leak is already used for per-org boot warnings in the
same file — the leak is bounded (one per hive-c0re boot, not per request)
so reusing it here is appropriate.
The rebuild call site in job_queue/exec.rs discards the bool return and
keeps its existing tracing::warn! lines, which is the right separation:
rebuilds are their own retry loop and don't need to post a persistent boot
warning.
