Cover two related v1.18 changes: dapr/dapr#9942 retunes the Scheduler's embedded etcd for workflow read/write profile: - etcd-snapshot-count 10000 -> 100000 - etcd-compaction-mode periodic -> revision - etcd-compaction-retention 10m -> 1000000 - etcd-backend-batch-limit 5000 -> 10000 - etcd-backend-batch-interval 50ms -> 100ms - new flag --etcd-max-txn-ops, default 10000 (etcd's own default is 128) - Helm cluster.storageSize default for fresh installs 1Gi -> 16Gi (existing installs keep their PVC size via lookup helper).

Pre-review for @marcduiker handoff: LGTM with nits.
- Scheduler etcd tuning defaults updated accurately: snapshot-count, compaction-mode/retention, batch-limit/interval, new
--etcd-max-txn-opsflag, and HelmstorageSizebump. All values match the linked dapr/dapr#9942. - Nit: the
storageSizedefault change (1Gi → 16Gi) is mentioned in the PR body but isn't reflected in the diff shown — worth confirming that section of the scheduler docs was updated or intentionally omitted. - Minor: deleted trailing blank line in placement.md is cosmetic; harmless.
Nothing blocking — Marc, your call.
