feat: persistency (#3880) * persistency: per-job SQLite-backed storage layer (singleton, brokered) Adds a backend-neutral CRUD library at waku/persistency/, plus the nim-brokers dependency swap that enables it. Architecture (ports-and-adapters): * Persistency: process-wide singleton, one root directory. * Job: one tenant, one DB file, one worker thread, one BrokerContext. * Backend: SQLite via waku/common/databases/db_sqlite. Uniform schema kv(category BLOB, key BLOB, payload BLOB) PRIMARY KEY (category, key) WITHOUT ROWID, WAL mode. * Writes are fire-and-forget via EventBroker(mt) PersistEvent. * Reads are async via five RequestBroker(mt) shapes (KvGet, KvExists, KvScan, KvCount, KvDelete). Reads return Result[T, PersistencyError]. * One storage thread per job; tenants isolated by BrokerContext. Public surface (waku/persistency/persistency.nim): Persistency.instance(rootDir) / Persistency.instance() / Persistency.reset() p.openJob(id) / p.closeJob(id) / p.dropJob(id) / p.close() p.job(id) / p[id] / p.hasJob(id) Writes (Job form & string-id form, fire-and-forget): persist / persistPut / persistDelete / persistEncoded Reads (Job form & string-id form, async Result): get / exists / scan / scanPrefix / count / deleteAcked Key & payload encoding (keys.nim, payload.nim): * encodePart family + variadic key(...) / payload(...) macros + single-value toKey / toPayload. * Primitives: string and openArray[byte] are 2-byte BE length + bytes; int{8..64} are sign-flipped 8-byte BE; uint{16..64} are 8-byte BE; bool/byte/char are 1 byte; enums are int64(ord(v)). * Generic encodePart[T: tuple \| object] recurses through fields() so any composite Nim type is encodable without ceremony. * Stable across Nim/C compiler upgrades: no sizeof, no memcpy, no cast on pointers, no host-endianness dependency. * `rawKey(bytes)` + `persistPut(..., openArray[byte])` let callers bypass the built-in encoder with their own format (CBOR, protobuf...). Lifecycle: * Persistency.new is private; Persistency.instance is the only public constructor. Same rootDir is idempotent; conflicting rootDir is peInvalidArgument. Persistency.reset for test/restart paths. * openJob opens-or-creates the per-job SQLite file; an existing file is reused with its data preserved. * Teardown integration: Persistency.instance registers a Teardown MultiRequestBroker provider that closes all jobs and clears the singleton slot when Waku.stop() issues Teardown.request. Internal layering: types.nim pure value types (Key, KeyRange, KvRow, TxOp, PersistencyError) keys.nim encodePart primitives + key(...) macro payload.nim toPayload + payload(...) macro schema.nim CREATE TABLE + connection pragmas + user_version backend_sqlite.nim KvBackend, applyOps (single source of write SQL), getOne/existsOne/deleteOne, scanRange (asc/desc, half-open ranges, open-ended stop), countRange backend_comm.nim EventBroker(mt) PersistEvent + 5 RequestBroker(mt) declarations; encodeErr/decodeErr boundary helpers backend_thread.nim startStorageThread / stopStorageThread (shared allocShared0 arg, cstring dbPath, atomic ready/shutdown flags); per-thread provider registration persistency.nim Persistency + Job types, singleton state, public facade ../requests/lifecycle_requests.nim Teardown MultiRequestBroker Tests (69 cases, all passing): test_keys.nim sort-order invariants (length-prefix strings, sign-flipped ints, composite tuples, prefix range) test_backend.nim round-trip / replace / delete-return-value / batched atomicity / asc-desc-half-open-open- ended scans / category isolation / batch txDelete test_lifecycle.nim open-or-create rootDir / non-dir collision / reopen across sessions / idempotent openJob / two-tenant parallel isolation / closeJob joins worker / dropJob removes file / acked delete test_facade.nim put-then-get / atomic batch / scanPrefix asc/desc / deleteAcked hit-miss / fire-and-forget delete / two-tenant facade isolation test_encoding.nim tuple/named-tuple/object keys, embedded Key, enum encoding, field-major composite sort, payload struct encoding, end-to-end struct round-trip through SQLite test_string_lookup.nim peJobNotFound semantics / hasJob / subscript / persistPut+get via id / reads short-circuit / writes drop+warn / persistEncoded via id / scan parity Job-ref vs id test_singleton.nim idempotent same-rootDir / different-rootDir rejection / no-arg instance lifecycle / reset retargets / reset idempotence / Teardown.request end-to-end Prerequisite delivered in the same series: replace the in-tree broker implementation with the external nim-brokers package; update all broker call-sites (waku_filter_v2, waku_relay, waku_rln_relay, delivery_service, peer_manager, requests/, factory/, api tests, etc.) to the new package API; chat2 made to compile again. Note: SDS adapter (Phase 5 of the design) is deferred -- nim-sds is still developed side-by-side and the persistency layer is intentionally SDS-agnostic. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * persistency: pin nim-brokers by URL+commit (workaround for stale registry) The bare `brokers >= 2.0.1` form cannot resolve on machines where the local nimble SAT solver enumerates only the registry-recorded 0.1.0 for brokers. The nim-lang/packages entry for `brokers` carries no per-tag metadata (only the URL), so until that registry entry is refreshed the SAT solver clamps the available-versions list to 0.1.0 and rejects the >= 2.0.1 constraint -- even though pkgs2 and pkgcache both have v2.0.1 cloned locally. Pinning by URL+commit bypasses the registry path entirely. Inline comment in waku.nimble documents the situation and the path back to the bare form once nim-lang/packages is updated.

Suite: 71 / 71 OK against the new async write surface.
