SDK Worker Registry & Fleet Resilience

This release introduces a unified in-process SDK worker registry that tracks live workers with heartbeats, sticky abort semantics, and disk projections — closing the liveness blind spots that left the scheduler, delegate queue, and worktree refresh timer unable to see workers running outside the bg executor. Alongside that, a Linear quota storm can no longer freeze fleet admission: when the circuit breaker is open, a provably-real replica-empty is now trusted directly instead of looping into a failing linearis reconfirm. Agent reads also move off the catalyst-linear CLI to direct SQLite queries against the local replica, giving agents full join support and a single, well-defined freshness rule; catalyst-linear is now a deprecated shim.
