⚡ Bolt: [Zero-Allocation Batch Query Parameters]

[ovasylenko]

💡 What: Updated the get_block_outputs_batch signature in orch8-storage to accept &[(InstanceId, &BlockId)] instead of &[(InstanceId, BlockId)]. Updated the caller in orch8-engine/src/scheduler.rs to pass references.
🎯 Why: Previously, the scheduler's deadline check fast-path collected pairs by calling deadline_keys.push((instance.id, step_def.id.clone())). Since BlockId wraps a String, this created thousands of unnecessary heap allocations per minute in highly concurrent setups.
📊 Impact: Eliminates BlockId string cloning on the scheduler tick hot-path for SLA checks, significantly reducing memory allocation overhead.
🔬 Measurement: Verified the compilation with cargo check and ensured all tests in orch8-engine and orch8-storage pass cleanly. Observe reduced heap allocations during scheduler ticks.

Closing as a duplicate of #53, which implemented the identical optimization (get_block_outputs_batch accepting &[(InstanceId, &BlockId)] to drop the per-tick BlockId clone). #53 was the only one of the four variants with fully-green CI (this one failed Check & Lint on an unrelated rustfmt diff in orch8-api/src/instances.rs), so it was merged. Thanks Bolt.
