04991295cf feat(abi,blocks): ninjatpl rendering as a host capability (powered blocks + tag/filter callbacks)
pongo2 stays host-side and is never compiled into a guest; plugins render
templates by handing the host a {template, data} pair, and the host calls
back into the free guest instance for plugin-declared tags/filters.

ABI (additive, buf-breaking clean):
- RenderBlockResponse gains a `powered` PoweredBlock{template, data_json};
  a block returns EITHER html OR powered.
- New hooks HOOK_RENDER_TAG (10) / HOOK_APPLY_FILTER (11) with
  RenderTag{Request,Response} and ApplyFilter{Request,Response}.
- PluginManifest gains repeated declared_tags / declared_filters (31/32).

Guest SDK (core/blocks, core/plugin/wasmguest):
- blocks.PoweredBlock(template, data) / DecodePoweredBlock: NUL-sentinel
  marker so BlockFunc's string signature is unchanged (smallest additive
  change — no ripple to existing blocks or the host guest-side).
- blocks.RegisterTag / RegisterFilter (+ RenderContext = context.Context)
  write a package-level registry; runRegister resets it per registration
  for deterministic DESCRIBE + dispatch.
- DESCRIBE emits declared_tags/filters; dispatch handles RENDER_TAG /
  APPLY_FILTER (fn errors → response.error; panics → AbiError INTERNAL,
  instance stays callable).

Docs: core/docs/wasm-abi.md gains the render-as-a-host-capability model,
the powered-block flow (re-entrancy-free), the plugin API, and the
HOST-SIDE CONTRACT the cms phase implements.

Tests: unit round-trips for powered/RENDER_TAG/APPLY_FILTER (dispatch +
error + unknown + panic + per-guest registry isolation) plus a real
wazero round-trip through the compiled fixture module. Verified no
guest-reachable package imports pongo2 (go list -deps on the wasip1
fixture build is clean).

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.
