feat(core): report scenario override outcomes

[92Infinitus92]

• Return a typed outcome for every scenario override.
• Report whether each override was applied or skipped, including the reason.
• Add outcome-aware time travel for pending overrides.
• Preserve RPC error classification and expose the new contract through the Node SDK.

Greptile Summary

The PR adds typed applied/skipped outcomes for scenario overrides and exposes outcome-aware registration, cancellation, and time travel through RPC and the Node SDK.

• Stages override materialization before atomically committing account changes and schedule removal.
• Batches cancellation updates across scheduled slots.
• Preserves invalid-parameter versus internal-error classification across runloop responses.
• Adds generated SDK types and methods for the new RPC contract.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview
crates/core/src/surfnet/svm.rs	Implements staged override materialization, batched cancellation, outcome reporting, and retry-aware time travel; the previously reported failures are resolved or explicitly accepted.
crates/core/src/storage/mod.rs	Extends the storage contract with batch and cross-table atomic operations used by override scheduling.
crates/core/src/storage/sqlite.rs	Implements transactional batch updates and atomic account/schedule commits for supported SQLite configurations.
crates/core/src/storage/postgres.rs	Implements transactional batch updates and cross-table schedule removal for PostgreSQL.
crates/core/src/rpc/surfnet_cheatcodes.rs	Exposes scenario outcomes, outcome-aware time travel, and scheduled-override cancellation through RPC.
crates/types/src/scenarios.rs	Defines the typed override outcome contract shared across core and SDK surfaces.
crates/sdk-node/surfpool-sdk/kit/generated/methods.ts	Exposes the new outcome-aware RPC methods through generated Node SDK bindings.
