feat(wire): Phase 867 protomux-rpc gossip migration (v0.8.834)

Browse Source 
Add protomux-rpc v2 gossip plane with PEARCORD_RPC_WIRE gate (default v1,
non-breaking). Centralize RPC constants, method keys, and attachGossipWireSession
in pearcord-drive/mux-wire; migrate guild/contacts/discovery/settings meshes.
Dual-stack and v2 roundtrip smokes; test:ci-phase867 bundle. Cutover to v2
default deferred (P867-49/50).

Guild peers multiplex **protomux** channels. RPC method ids are centralized in `pearcord-shared` (`RPC.MESSAGE_CREATE`, `RPC.GUILD_SYNC`, `RPC.VOICE_SPEAKING`, …). The guild module emits events; `pearcord-platform` subscribes and updates `LocalDatabase` + in-memory caches. Guild peers multiplex **protomux** channels. Gossip uses wire **v1** by default (`encodeRpc` compact frames on `*-v1` protocols). Wire **v2** ([protomux-rpc](https://www.npmjs.com/package/protomux-rpc), string method keys on `*-rpc-v2` protocols) is opt-in via `PEARCORD_RPC_WIRE=v2` or dual-stack `dual`. See [PROTOMUX_RPC_MIGRATION.md](./PROTOMUX_RPC_MIGRATION.md).

# Protomux-RPC wire migration (Phase 867)
Pearcord gossip meshes historically used `pearcord-drive/mux-wire` `openWireChannel` with v1 compact-encoding frames (`encodeRpc` / `decodeRpc` in `pearcord-shared`). Phase 867 adds [protomux-rpc](https://www.npmjs.com/package/protomux-rpc) (`^1.10.0`) as wire **v2** on parallel protocol names while preserving v1 until cutover.
## Wire versions
| Version | Env | Channel protocol | Framing |
|---------|-----|------------------|---------|
| v1 (default) | `PEARCORD_RPC_WIRE=v1` or unset | `*-v1` (e.g. `pearcord-gossip-v1`) | `uint8 method` + JSON payload buffer |
| v2 | `PEARCORD_RPC_WIRE=v2` | `*-rpc-v2` (e.g. `pearcord-gossip-rpc-v2`) | protomux-rpc `event` / `request` / `respond` with string method keys |
| dual-stack | `PEARCORD_RPC_WIRE=dual` | Both channels on same Hyperswarm connection | Send/receive on v1 and v2 |
v1 and v2 are **not** compatible on the same protocol name. Dual-stack opens **two** protomux channels per mesh plane.
## Shared mux
`Protomux.from(stream)` caches the mux on `stream.userData`. Multiple `ProtomuxRPC(conn, { protocol })` instances on one connection share the same mux (gossip, contacts, discovery, attach, voice, etc.).
## Method naming (P867-6)
Numeric `RPC.*` ids map 1:1 to string keys via `pearcord-shared/rpc-method-keys.js` (e.g. `1` → `MESSAGE_CREATE`). Inbound v2 events decode to numeric ids before `_onGossip` dispatch so guild/contacts handlers stay unchanged.
## Request/response semantics (P867-2)
These pairs use request/response **semantics** on gossip (v1: fire-and-forget broadcasts; v2: may use `rpc.request` / `rpc.respond` in a later sub-step):
- `GUILD_SYNC_REQUEST` / `GUILD_SYNC`
- `MEMBER_PAGE_REQUEST` / `MEMBER_PAGE`
- `MESSAGE_SEARCH_REQUEST` / `MESSAGE_SEARCH_RESPONSE`
- `DEVICE_PAIR_REQUEST` / `DEVICE_PAIR_BUNDLE`
- `AUDIT_EXPORT_ARCHIVE_REQUEST` / `AUDIT_EXPORT_ARCHIVE`
- `AUTOMATION_DIGEST_EXPORT_SNAPSHOT_REQUEST` / `AUTOMATION_DIGEST_EXPORT_SNAPSHOT`
All other `RPC.*` methods are event-only.
## Media planes (P867-28–30)
**Deferred on v2 for Phase 867:** `attach-mesh`, `voice-media`, and `screen-share` remain on `openWireChannel` + JSON `{ op }` buffer messages. Evaluate protomux-rpc migration in a follow-up sub-phase.
## Call sites (P867-1)
| Module | File | Protocol v1 |
|--------|------|-------------|
| `pearcord-guild` | `mesh.js` | `pearcord-gossip-v1` |
| `pearcord-dm` | re-exports guild mesh | (same) |
| `pearcord-bot-runner` | `index.js` via guild mesh | (same) |
| `pearcord-discovery` | `mesh.js` | `pearcord-discovery-v1` |
| `pearcord-contacts` | `mesh.js` | `pearcord-contacts-v1` |
| `pearcord-settings` | `mesh.js` | `pearcord-userprefs-v1` |
| `pearcord-settings` | `mesh-health.js` | `pearcord-settings-health-v1` |
| `pearcord-notifications` | `mesh.js` | `pearcord-settings-v1` |
| `pearcord-device-sync` | `mesh.js` | `pearcord-device-sync-v1` |
| `pearcord-profile-cosmetics` | `mesh.js` | `pearcord-profile-cosmetics-v1` |
| `pearcord-drive` | `attach-mesh.js` | attach (v1 only) |
| `pearcord-voice-media` | `mesh.js` | `pearcord-voice-v1` |
| `pearcord-screen-share` | `mesh.js` | `pearcord-screen-v1` |
## Cutover (P867-49)
1. Run `npm run test:ci-phase867` with `PEARCORD_RPC_WIRE=v2` and `dual`.
2. When green, default env to v2 and remove dual-stack bridge.
3. Remove legacy `encodeRpc` gossip paths after all peers ship v2.
## Diagnostics
- `PEARCORD_MESH_RPC_WIRE_LOG=1` — stderr `mesh.rpc.wire` lines with wire version + method.
- Voice UI engine badge includes `protomux-rpc` when v2 wire is active (`voiceMedia.engine`).
