fix(spec,core,cloud-connection,metadata): one HTTP contract, one canonical slot name (#4251)

packages/core/src/contracts/ was a dead near-copy of the real contracts --
zero importers (no relative import, no subpath export, not a tsup entry;
core's barrel has re-exported the spec versions all along) -- and it had
already DIVERGED (spec's IHttpResponse grew write?/end?, IHttpRequest grew
rawBody?; the copy never did). Anyone who grepped into it read a stale
contract nothing enforces -- the both-humans-and-AI failure mode behind
the false http.server exemption (#4382). Deleted; zero-risk by
construction.

`http.server` is the canonical slot name and the ledger now says so:
ServiceSlotContracts gains 'http.server': IHttpServer plus the deprecated
'http-server' alias entry (same instance -- hono-plugin, qa node-plugin
and cloud's two server entrypoints all register both, alias commented
"backward compatibility"). Canonical is the only name on EVERY provider
path -- runtime's config.server path registers no alias, so the three
cloud-connection plugins reading the alias alone found an empty slot
there. All readers now go canonical-first with the alias as a fallback
that dies with the alias registrations; registrations untouched this
release, both sites carry the deprecation note.

getRawApp?(): any joins IHttpServer -- the deliberate framework-handle
escape, declared once with the rationale; four consumers declared it
locally before (cloud-connection x2, metadata HMR, cloud node-server),
and the local RawAppHost / HttpServerWithRawApp types are deleted.

IMetadataService.bulkRegister/bulkUnregister declare the write options
their implementation always accepted (bulkRegister's contract dropped the
MetadataWriteOptions half it intersects in; bulkUnregister declared no
options at all). Same shape as B2's IDataEngine read-methods gap.

Baseline 168 -> 167 (marketplace-install-local's lookup typed while
touched). Ledger test pins both slot entries and the alias equality.

Verified: spec build (dts) + 7192 tests / 281 files; core, metadata,
cloud-connection, plugin-hono-server dts builds; runtime 1001/69, rest
539/36, plugin-auth 579/26, plugin-sharing 226/11, service-settings
196/14, metadata 281/13, hono-server 135/12, http-conformance 46/2;
ratchet holds 167/36 none new; eslint clean.

+fix(spec,core,cloud-connection,metadata): one HTTP contract, one canonical slot name — and the dead shadow copy that helped cause the false exemption is deleted (#4251)
+
+**`packages/core/src/contracts/` was a dead near-copy of the real contracts,
+and it is gone.** The directory (http-server.ts, data-engine.ts, logger.ts) had
+ZERO importers — no relative import, no subpath export, not a tsup entry;
+core's barrel has re-exported the `@objectstack/spec/contracts` versions all
+along ("Re-export contracts from @objectstack/spec for backward
+compatibility"). But the shadow had already **diverged** from the live
+contract (spec's `IHttpResponse` grew `write?`/`end?` and `IHttpRequest` grew
+`rawBody?`; the copy never did), so anyone who grepped their way into it read a
+stale contract that nothing enforces — the exact both-humans-and-AI failure
+mode behind the false `http.server` exemption (#4382). Deleting it is
+zero-risk by construction: nothing could reach it.
+
+**`http.server` is the canonical slot name, and the ledger now says so.**
+`ServiceSlotContracts` gains `'http.server': IHttpServer` plus the deprecated
+`'http-server'` alias entry (same instance — hono-plugin and qa's node-plugin
+register both two lines apart; cloud's two server entrypoints do the same).
+Canonical is the only name present on EVERY provider path: runtime's
+`config.server` path registers no alias, so the three cloud-connection plugins
+that read the alias alone (marketplace-proxy, runtime-config,
+marketplace-install-local) found an empty slot there — a live miss, now fixed:
+all readers go canonical-first with the alias as a fallback that dies with the
+alias registrations. The registrations themselves are untouched this release;
+both sites now carry the deprecation note.
+
+**`getRawApp?(): any` joins `IHttpServer`** — the deliberate framework-handle
+escape, declared once. Four consumers were each declaring it locally
+(cloud-connection ×2, metadata's HMR routes, cloud's serverless node-server);
+those local `RawAppHost`/`HttpServerWithRawApp` types are deleted. The `any`
+return is deliberate and documented at the single declaration: the handle's
+real type belongs to the framework, and naming it would give the contract a
+framework dependency. Adapters are not required to expose it; consumers
+feature-detect.
+
+**`IMetadataService.bulkRegister`/`bulkUnregister` declare the write options
+their implementation has always accepted.** `bulkRegister`'s contract options
+dropped the `MetadataWriteOptions` half its implementation intersects in
+(`notify` is destructured on the method's first line); `bulkUnregister`
+declared no options at all while the manager takes them. Same shape as the
+`IDataEngine` read-methods gap from B2: a caller typed to the contract could
+not reach the channel without erasing the lookup. Both additive; no implementor
+or caller breaks.
+
+Slot-lookup baseline ratchets 168 → 167 (marketplace-install-local's lookup
+typed while touched).
