docs: update CLAUDE.md for core/wormkit split and SoundId unification

Update crate descriptions and Key Files to reflect game logic now
living in openwa-core (weapon_fire, weapon_release, sound_ops,
team_ops) with wormkit as thin hook shims. Update SoundId description
to document packed format (slot + flags).

 ## Crate Architecture
 
-- **`openwa-core`** — Types, addresses, parsers, ASLR rebasing, and typed WA function wrappers. The source of truth for all reverse-engineered type layouts and known addresses. Contains `registry` (structured address database + field registries), `rebase` (ASLR delta), `wa_call` (calling convention helpers), and `wa/` (typed handle wrappers like `DDGameWrapperHandle`, `CWndHandle`).
+- **`openwa-core`** — Types, addresses, parsers, ASLR rebasing, typed WA function wrappers, **and game logic**. The source of truth for all reverse-engineered type layouts, known addresses, and Rust reimplementations of WA functions. Contains `registry` (structured address database + field registries), `rebase` (ASLR delta), `wa_call` (calling convention helpers), `wa/` (typed handle wrappers), and game logic modules (`game/weapon_fire.rs`, `game/weapon_release.rs`, `audio/sound_ops.rs`, `engine/team_ops.rs`).
 - **`openwa-derive`** — Proc macro crate. Provides `#[derive(FieldRegistry)]` for struct field maps and `#[vtable(...)]` for typed vtable definitions with introspection, calling wrappers, and replacement support.
-- **`openwa-wormkit`** — Unified WormKit cdylib that replaces WA functions with Rust. Logs to `OpenWA.log`. Uses MinHook for inline hooking. Runs registry-driven startup checks (vtable locations, function prologues) automatically at load; the test runner reports any failures after the test summary.
+- **`openwa-wormkit`** — Unified WormKit cdylib: thin hook installation shims (trampolines, `usercall_trampoline!`, `install()`) that wire core's game logic into WA.exe via MinHook. Logs to `OpenWA.log`. Runs registry-driven startup checks automatically at load.
 - **`openwa-test-runner`** — Headless replay test runner (`openwa-test` binary). Discovers replay tests, runs them concurrently via WA.exe's `/getlog` mode, compares output logs. See "Replay Testing" section.
 - **`openwa-debug-cli`** — CLI tool for live memory inspection (`openwa-debug` binary). Connects to the debug server in the DLL.
 - **`openwa-debug-proto`** — Shared protocol types (Request/Response enums, MessagePack framing) between CLI and server.
