Alex Dunmow 704b046727 feat(abi): wasm plugin ABI protobuf schema v1 (WO-WZ-001)
Defines the host<->guest wire contract for the .so -> wazero migration as a
repo-local buf module (abi/proto/v1, generated Go in abi/v1):

- manifest.proto: PluginManifest mirroring every static field of
  plugin.PluginRegistration (abi_version, deps, block/template registrations,
  admin pages, settings schema, theme presets, fonts, master pages, AI
  actions, RBAC method roles, CSS manifest, icon packs, directory
  extensions, job types, RAG fetcher types, settings panel, hook flags,
  core service bindings)
- invoke.proto: bn_invoke envelope, Hook catalog (RENDER_BLOCK,
  RENDER_TEMPLATE, HANDLE_HTTP, JOB, LOAD, UNLOAD, RAG_FETCH, MEDIA_HOOK,
  DESCRIBE), AbiError, and job/lifecycle/rag/media/describe payloads
- render.proto: RenderBlock/RenderTemplate payloads + RenderContext
  enumerating every ctx value from blocks/context.go (incl. BlockContext 1:1)
- http.proto: buffered HttpRequest/HttpResponse for HANDLE_HTTP
- db.proto: guest sql-driver messages (DbValue oneof over pgx-mappable
  types, query/exec/tx with host-side tx handles, SQLSTATE-carrying DbError)
- capability.proto: HostCall envelope + one request/response pair per
  CoreServices interface method (content, settings+update, gating, crypto,
  menus, datasources, users, subscriptions, media.deposit, email.send,
  ai.text_call, ai.tools.register, bridge, jobs.submit, embeddings, rag,
  reviews, badges.refresh)

The abi/ buf module is deliberately separate from the repo-root config:
proto/ is the shared block/proto submodule (service API contracts); the ABI
is SDK-internal and versions in lockstep with the guest shim. New `make abi`
target runs buf lint + generate. docs/wasm-abi.md documents the ptr+len
calling convention (bn_alloc, bn_invoke, packed u64), hook catalog, error
semantics, abi_version evolution rules, and the full registration/
CoreServices coverage tables.

Verified: `cd abi && buf lint` exit 0; `go build ./...` exit 0.

# Buf module for the wasm plugin ABI (WO-WZ-001).
#
# Deliberately separate from the repo-root buf.yaml: that one wraps the
# proto/ git submodule (shared block/proto service contracts), while this
# ABI is SDK-internal and versions in lockstep with the guest shim, so it
# lives repo-local under abi/proto. Run buf from this directory (`make abi`
# at the repo root).
