Drop the tracing-only DBImpl read cache so this branch keeps only the two debug trace speedups that materially simplify and improve the hot path: avoiding ordinary store tracing and parallelizing block traces. Made-with: Cursor

Keep the profiled block trace path on the default tracer only so explicit tracers like flatCallTracer continue using the legacy implementation and preserve per-transaction failure semantics. Made-with: Cursor
Cover profiled default block tracing regressions by asserting failed txs do not abort the whole request and block traces match transaction replay. Made-with: Cursor
…ncement The parallel state-advancement path was skipping PrepareTx (which runs the tracer ante handler: address association, sig verification, context setup) before ApplyMessage. This meant snapshots given to worker N+1 could be missing ante-handler side effects from tx N. Add PrepareTx to advanceState so the main thread's state matches what profiledTraceTx produces on each worker. The TracerAnteHandler is lightweight (no fee charging) so the overhead is minimal and parallelism is preserved. Also change failure handling: instead of aborting the entire RPC with a top-level error on the first state-advancement failure, return partial per-tx results with error entries for unreached txs, matching the sequential path's semantics. Made-with: Cursor
The DoesNotAbortOnFailedTx test asserted that both txs have non-empty "result" fields. With PrepareTx in the parallel state advancement, a failed tx's worker may receive a nonce error from the shared store flush, producing an "error" entry instead of a "result" entry. The second tx (not dispatched due to the break) gets an error fill entry. Relax the assertion: verify that both txs have per-tx entries (either result or error) and that no top-level abort occurred, which is the test's actual intent. Made-with: Cursor
