Adds the failure-ticket + recovery-routing mechanism: a deterministic gate->capability table gates whether a stage has agency to fix its own failure, opens a FailureTicketOpenedEvent when it doesn't, and routes to a metadata role=recovery stage (per-stage budget, cap 2, not reset by TransitionExecuted) instead of retrying in place. Extends salvage decisions with a RECOVER option so the review-gate judge can also route to recovery, unifies deterministic-gate and review-gate routing through routeToRecovery(), and has ExecutionPlanCompiler synthesize a write-capable recovery stage + edge for freestyle plans. Read-only tools (file_read, list_dir) are now always available on any tool-granting stage so a recovery stage can inspect the write-less stage's failure without flooding context via shell ls -R.
