feat(mix): integrate mix protocol with extended kademlia + RLN spam protection
Rebased poc/mix-spam-protection onto origin/master. Bundles:

- Extended kademlia discovery integration for mix node pool
  (waku/discovery/waku_kademlia.nim, tools/confutils/cli_args.nim)
- RLN spam protection plugin (vacp2p/mix-rln-spam-protection) wired in:
  WakuMix gains mixRlnSpamProtection + publishMessage callback,
  per-hop proof generation / verification, membership coordination
  via /mix/rln/metadata/v1 content topic
- chat2mix sim app: filter-subscribes to spam-protection coordination
  topic, defers publishing until mix node pool is populated
- Makefile: automated librln_mix_v2.0.0.a build via
  scripts/build_rln_mix.sh and mix-librln target
- simulations/mixnet: 5-node mixnet sim infrastructure
  (config1-4.toml, run_*.sh, build_setup.sh, setup_credentials.nim,
  README, roundtrip_check.sh automated round-trip verification)

Rebase fixes:
- Plugin previously vendored as submodule; now a nimble requires entry
  pinned to logos-co/mix-rln-spam-protection-plugin@037f8e10
- waku.nimble: zlib < 0.2 pin to keep nimble lock resolution stable
  (upstream zlib HEAD bumped to 0.2.0)
- apps/chat2mix/config_chat2mix.nim: replace
  `defaultValue: parseIpAddress("...")` with IpAddress literal,
  works around confutils macro generating
  `defaultValueHelpName(): string {.raises: [].}` that violates the
  raises pragma when stringifying a parseIpAddress call
- config.nims: nimble setup --noNimblePath reordering
