### Breaking Changes
- Removed fees from locked balance calculations for `CASH` accounts
- Removed fees from margin calculations for `MARGIN` accounts
- Renamed `id` constructor parameter to `instrument_id` across all PyO3 instruments, aligning with equivalent Cython instrument constructors

### Internal Improvements
- Implemented exponential backoff and jitter for the `RetryManager` (#2518), thanks @davidsblom
- Simplified default locked balance and margin calculations to not include fees
- Improved handling of time range and effective date filters for `TardisInstrumentProvider`
- Improved reconnection robustness for Bybit private/trading channels (#2520), thanks @sunlei
- Improved logger buffers flushing post backtest
- Improved validations for Tardis trades data
- Improved correctness of client registration and deregistration for `ExecutionEngine`
- Improved build time by only compiling libraries (#2539), thanks @twitu
- Improved logging flush (#2568), thanks @faysou
- Improved `clear_log_file` to happen for each kernel initialization (#2569), thanks @faysou
- Refined `Price` and `Quantity` validations and correctness
- Filter fill events if order is already filled for dYdX (#2547), thanks @davidsblom
- Fixed some clippy lints (#2517), thanks @twitu
- Upgraded `databento` crate to v0.24.0
- Upgraded `datafusion` crate to v47.0.0
- Upgraded `redis` crate to v0.30.0
- Upgraded `sqlx` crate to v0.8.5
- Upgraded `pyo3` crate to v0.24.2

### Fixes
- Fixed consistent ordering of execution events (#2513, #2554), thanks for reporting @stastnypremysl
- Fixed type error when generating an elapsed time for backtests with no elapsed time
- Fixed memory leak in `RetryManager` by simplifying the acquire-release pattern, avoiding the asynchronous context manager protocol that led to state sharing, thanks for reporting @DeevsDeevs
- Fixed locked balance and initial margin calculations for reduce-only orders (#2505), thanks for reporting @stastnypremysl
- Fixed purging order events from position (these needed to be purged prior to removing cache index entry), thanks @DeevsDeevs
- Fixed `TypeError` when formatting backtest post run timestamps which were `None` (#2514), thanks for reporting @stastnypremysl
- Fixed handling of `BetfairSequenceCompleted` as custom data
- Fixed the instrument class of `IndexInstrument`, changing to `SPOT` to correctly represent a spot index of underlying constituents
- Fixed data range request `end` handling for `DataEngine`
- Fixed unsubscribe instrument close for `DataEngine`
- Fixed network clients authentication for OKX (#2553), thanks for reporting @S3toGreen
- Fixed account balance calculation for dYdX (#2563), thanks @davidsblom
- Fixed `ts_init` for databento historical data (#2566), thanks @faysou
- Fixed `RequestInstrument` in `query_catalog` (#2567), thanks @faysou
- Reverted removal of rotate log file on UTC date change (#2552), thanks @twitu

### Documentation Updates
- Improved environment setup guide with recommended rust analyzer settings (#2538), thanks @twitu
- Fixed alignment with code for some `ExecutionEngine` docstrings

### Deprecations
