feat(mix): bump libp2p stack to v2.0.0 + adopt stateless RLN spam protection
Combines five dep-and-build changes that all flow from the libp2p v2.0.0
upgrade and the move to the extracted libp2p_mix / mix-rln plugin stack:

waku.nimble:
  * libp2p: ff8d51857 -> c43199378 (release/v2.0.0 tip; sha-pinned until
    vacp2p cuts a v2.0.0 tag).
  * Drop the bare `zlib < 0.2` cap — no longer needed by the upgraded
    libp2p.
  * websock: bare ">= 0.4.0" — replaces the d4cd68b URL+SHA workaround
    that pinned through a libp2p commit-specific websock SHA.
  * nim-json-rpc: switch to chaitanyaprem/nim-json-rpc#f05fad25 — relaxes
    websock cap to allow >=0.4.0. TODO: revert to status-im/nim-json-rpc
    once status-im/nim-json-rpc#277 merges and a tag is cut.
  * lsquic: bare ">= 0.4.1" (drops URL form).
  * Add mix-rln-spam-protection-plugin pin (23b278b4) and nim-libp2p-mix
    pin (50c4ab4f — PR #14 HEAD); the plugin pins the same libp2p_mix
    SHA so the diamond dep collapses to a single source.

waku/factory/waku.nim:
  * Explicit HPService.setup(switch) / AutonatService.setup(switch)
    calls. libp2p v2.0.0's Service lifecycle refactor (libp2p#2462)
    removed switch.start's auto-setup loop, so any caller that assigns
    directly to switch.services (we do) is responsible for calling
    setup() themselves. Without it, AutonatService.addressMapper stays
    nil and peerInfo.expandAddrs SIGSEGVs during start(). Wrapped in
    try/except for ServiceSetupError so a setup failure surfaces as a
    logged error rather than a crash.

Build / scripts:
  * scripts/build_rln_mix.sh removed and Makefile simplified — librln
    is now a single shared archive built from zerokit's `stateless`
    features (no separate librln_mix archive).
  * simulations/mixnet/build_setup.sh + setup_credentials.nim updated
    to use librln_v2.0.2.a directly and run RLN keystore setup before
    nodes start.

Validated:
  * Cold local-cache nimble setup --localdeps -y.
  * wakunode2 and chat2mix link cleanly.
  * Mixnet roundtrip sim: [PASS] bob received message from alice.
  * RLN proof generation + verification on every in-path mix node:
    5 gen_called == 5 verified, 0 SPAM_PROOF_* errors.

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)

                         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.

* 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.

* persistency: nph format pass

Run `nph` on all 57 Nim files touched by this PR. Pure formatting:
17 files re-styled, no semantic change. Suite still 69/69.

* persistency tests: migrate to suite / asyncTest / await

Match the in-tree test convention (procSuite -> suite, sync test +
waitFor -> asyncTest + await):

- procSuite "X": -> suite "X":
- For tests doing async work: test -> asyncTest, waitFor -> await.
- Poll helpers (proc waitFor(t: Job, ...) in test_lifecycle.nim,
  proc waitUntilExists(...) in test_facade.nim and
  test_string_lookup.nim) -> Future[bool] {.async.}, internal
  `waitFor X` -> `await X`, internal `sleep(N)` ->
  `await sleepAsync(chronos.milliseconds(N))`.
- Renamed test_lifecycle.nim's helper proc from `waitFor(t: Job, ...)`
  -> `pollExists(t: Job, ...)`; the previous name shadowed
  chronos.waitFor in the chronos macro expansion.
- `chronos.milliseconds(N)` explicitly qualified because `std/times`
  also exports `milliseconds` (returning TimeInterval, not Duration).
- `check await x` -> `let okN = await x; check okN` to dodge chronos's
  "yield in expr not lowered" with await-as-macro-argument.
- `(await x).foo()` -> `let awN = await x; ... awN.foo() ...` for the
  same reason.

waku/persistency/persistency.nim: nph also pulled the proc signatures
across multiple lines; restored explicit `Future[void] {.async.}`
return types after the colon (an intermediate nph pass had elided them).

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