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 them through scenario registration, time travel, shared RPC contracts, and the Node SDK.

• Adds atomic scheduling and staged materialization across in-memory, SQLite, and PostgreSQL storage.
• Preserves invalid-parameter versus internal-error classification across the command channel.
• Adds focused regression coverage for replacement, materialization, retry, and time-travel behavior.

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 atomic scenario replacement, staged override materialization, outcome reporting, and retry-aware time travel; the previously reported failure paths are resolved or intentionally recoverable.
crates/core/src/storage/mod.rs	Extends the storage contract with batched operations and cross-table removal needed for atomic account and schedule commits.
crates/core/src/storage/sqlite.rs	Implements batch and cross-table operations inside SQLite transactions with rollback coverage.
crates/core/src/storage/postgres.rs	Implements equivalent transactional batch behavior for PostgreSQL.
crates/core/src/rpc/surfnet_cheatcodes.rs	Returns typed override outcomes from scenario registration and time travel while preserving RPC error conversion.
crates/types/src/scenarios.rs	Defines the shared serialized override outcome contract.
crates/types/src/types.rs	Extends command and time-travel response contracts to carry override outcomes and classified errors.
crates/sdk-node/surfpool-sdk/kit/types/api.ts	Updates the Node SDK cheatcode API to expose the new scenario and time-travel result shapes.
crates/sdk-node/surfpool-sdk/kit/generated/OverrideOutcome.ts	Adds the generated TypeScript representation of applied and skipped override outcomes.
