### Breaking Changes
- Renamed custom-data field marker `json` to `serde` (#4133), thanks @faysou
- Removed live engine `graceful_shutdown_on_error`; use node-level `shutdown_on_error` instead
- Changed `nautilus_pyo3.get_exchange_rate` to return `decimal.Decimal` instead of `float`
- Changed DeFi pool-event and snapshot types to require `ts_event`/`ts_init` timestamps (was optional `timestamp`)
- Changed `PoolProfiler::initialize` and `check_if_initialized` to return `Result` rather than assert
- Changed command `new` constructors to accept `correlation_id: Option<UUID4>`, pass `None` for old behavior (Rust)
- Changed `CVec` to no longer implement `Send`; use typed wrappers for thread transfer (Rust)
- Changed Hyperliquid HIP-4 outcome `InstrumentId` to `{outcome_index}-{YES|NO}-OUTCOME.HYPERLIQUID`
- Changed Deribit `DeribitWebSocketClient.with_credentials` to accept `api_key`/`api_secret` after `environment`
- Changed order event `reconciliation` and `due_post_only` from `u8` to `bool` (changes JSON/Arrow schemas)
- Changed Deribit combos to land as `CryptoOptionSpread`/`CryptoFuturesSpread` instead of `OptionSpread`/`FuturesSpread`; `FuturesSpread`/`OptionSpread` once again guarantee whole-contract sizing

### Release completion note
The automated `publish-release-integrity` job did not complete for this release. Cargo crate publishing was recovered after manually publishing these crates with a short-lived crates.io token: `nautilus-analysis`, `nautilus-common`, `nautilus-execution`, `nautilus-lighter`, `nautilus-network`, `nautilus-portfolio`, `nautilus-testkit`, and `nautilus-trading`. Those crate versions therefore show crates.io `published_by` metadata rather than Trusted Publishing metadata. The final integrity assets, including `crates-manifest.json` and attestation sibling files, were attached manually after PyPI/Sigstore verification continued to fail on CI despite the affected wheel verifying locally.
