chore: refresh README crate table + lock op-web-daemon entry

Deferred from the prior commits (both were co-edited with the concurrent actor
at the time): README's stale crate list -> accurate op-* entry-crates table
(matching the cargo:wasm-check fix), and the op-web-daemon Cargo.lock package
entry (hunk-staged to exclude the concurrent op-web-sdk changes still in flight).

+**Shared library crates:** `op-editor-core` (canonical `.op` state), `op-editor-ui` (platform-free widgets + `RenderBackend`), `op-editor-host-core` (transport-free host state machines), `op-mcp`, `op-ai`, `op-ai-skills`, `op-codegen`, `op-orchestrator`, `op-figma`, `op-git`, `op-opmerge`, `op-pen-loader`, `op-design-lint`, `op-config-store`, `op-process-io`, `op-acp`, `op-i18n`, `op-rpc-transport` — plus `op-smoke` (headless design-turn test runner). The browser bundle renders through the official CanvasKit skia WASM (loaded separately), so the retired `skia-safe-op` wasm fork + `wasm-libc-shim` no longer exist.
 
 **Submodule:** `vendor/agent` → `github.com/ZSeven-W/agent-rs` (cross-product Rust agent runtime).
