Squashes every fuzzing-infrastructure change in this branch into one commit, separate from the individual bug fixes the fuzzing surfaced (one commit each): * The cargo-fuzz crates under `src/*/fuzz` — targets, seed corpora, dictionaries, and `prepare-corpus.sh` scripts — covering the SQL parser / pretty-printer, repr (strconv, jsonb, Row codec/proto, arithmetic oracles), the expr optimizer transforms, Avro/Protobuf/CSV/pgwire/pgcopy decoders, pgrepr/pgtz, the upsert state machine, persist durable-state decode, and the proto round-trips across storage-types/persist/catalog/external table descs. * The harness and runner wiring: `--profile fruitful`, `--jobs auto`, per-crate sharding, artifact-based crash detection, `.repro.txt` sidecars, and the auto-generated `buf.yaml` fuzz-crate excludes. * CI: move cargo-fuzz from nightly to release qualification (24h, 48-core). * The production-side enablement the targets require: the `fuzzing`/`fuzz` Cargo features and the `#[doc(hidden)]` / `cfg`-gated re-exports that expose upsert, persist-client, and pgwire internals to the fuzz crates. * The macOS build fixes those exports necessitated: raising and then removing the storage `recursion_limit` workaround by switching the affected `Stream::inspect` calls to `InspectCore::inspect_container`, which avoids the objc2-driven trait-solver overflow. * The sqllogictest/testdrive golden updates for the identifier-quoting changes.

Adds the cargo-fuzz suite: fuzz targets, seed corpora, dictionaries, and the runner/CI integration (release-qualification, 24h). Covers the SQL parser/pretty-printer, repr (strconv, jsonb, Row codec/proto, arithmetic oracles), the expr optimizer transforms, the Avro/Protobuf/CSV/pgwire/pgcopy decoders, pgrepr/pgtz, the upsert state machine, persist durable-state decode, and proto round-trips across storage-types/persist/catalog/external table descs.
Also includes the production-side enablement the targets require (the
fuzzing/fuzzCargo features and#[doc(hidden)]/cfg-gated re-exports) and the macOS build fixes those exposures necessitated.This is the infrastructure PR — mostly mechanical (generated corpora/dicts). The individual bugs it surfaced are split into separate per-subsystem PRs.
Depends on #36983, #36984, #36985, #36986, #36987
