Two-layer retry for transient acpx review failures. Layer 1 (acpx): runAcpxJson now passes --prompt-retries <n> (default 1) so the underlying agent can recover stream cuts and partial JSON internally without the whole feature failing. Override via CLAWPATCH_ACPX_PROMPT_RETRIES; 0 disables. Layer 2 (clawpatch): reviewFeature wraps provider.review() in a single retry that fires only on ClawpatchError with code === "malformed-output". Override via CLAWPATCH_REVIEW_RETRIES; 0 disables. Deterministic failures (provider-auth, unsupported-provider, agent-refused, agent-cancelled) and provider-failure (already covered by layer 1) are not retried at this layer. The retry is inside reviewFeature so the work-stealing loop in runReview does not double-claim the feature lock. Emits a "feature-retry" progress event between attempts.

Summary
reviewFeaturehas a single attempt — anyprovider.review()failure marks the feature errored, even when the cause is a transient stream cut. acpx itself supports--prompt-retries <n>but clawpatch never sets it.This PR adds two cheap retry layers, both opt-out via env var:
runAcpxJsonpasses--prompt-retries <n>(default 1; envCLAWPATCH_ACPX_PROMPT_RETRIES;0omits the flag).runProviderReviewWithRetrywrapsprovider.reviewand retries ONCE onClawpatchError && code === "malformed-output". Default 1; envCLAWPATCH_REVIEW_RETRIES.Excluded codes (deterministic, won't retry):
provider-auth,unsupported-provider,agent-refused,agent-cancelled.The new upstream
validateReviewOutput()step runs AFTER the retry succeeds — validation failures are NOT retried (they're per-finding bugs, not transient).Why
Run

Worst-case latency on a stuck feature with both retry layers maxed: 2 acpx tries × 2 clawpatch tries × 3 min default timeout = 12 min.
CLAWPATCH_ACPX_TIMEOUT_MSis the safety valve. With default 10-jobs concurrency the bound is acceptable.
