Alex Dunmow bec3a43f55 feat(wasmguest): guest capability stubs over host calls (WO-WZ-003)
Every CoreServices interface (core/plugin/deps.go) now has a guest-side stub
that marshals to the WO-WZ-001 capability messages and dispatches through the
generic host_call transport, so plugin service code compiles and runs
unchanged against content.Content, settings.Settings, plugin.PluginBridge, etc.

- core/plugin/wasmguest/caps/: one file per family (17 families, 38 methods),
  a var _ <iface> = (*stub)(nil) compile proof each, and NewCoreServices(call)
  assembling them. The transport is injected (CallFunc) so marshaling is
  natively testable; the wasm shim binds it to CallHost, DESCRIBE probes pass
  nil (capability calls fail cleanly instead of nil-panicking).
- Error mapping wraps AbiError with <family>.<method> context and maps
  DEADLINE_EXCEEDED onto context.DeadlineExceeded.
- RAGService.RegisterContentFetcher stays guest-side (RAGStub) for
  HOOK_RAG_FETCH dispatch; Query/OnContentChanged marshal out. dispatch.go and
  describe.go now source fetchers from the caps RAG stub.
- caps_roundtrip_test.go: fake transport + 76 deterministic golden payloads
  (family_method_{req,resp}.pb) covering 100% of families, plus error-mapping,
  deadline, nil-transport, and guest-side-fetcher tests. WO-WZ-006 replays the
  same goldens to prevent host/guest drift.
- Acceptance: testdata/fixture Load hook calls deps.Content/Settings/Bridge
  unchanged (compiles for wasip1); caps_wasmhost_test.go drives it end-to-end
  through a real wazero module + fake host_call table.
- Disposition table in docs/wasm-abi.md: every member stub | host-side
  (Pool, Interceptors, AppURL/MediaPath, CoreServiceBindings host-side).
