Build GE-Enforce manifest-store plugin (P0/P1): model, importer, parity gate

First execution phases of docs/proposals/ge-enforce-plugin.md. The GE-Enforce
manifest becomes shopdb data.

P0 scaffold: new geenforce plugin (api_prefix /api/geenforce, default_enabled
false, core_version >=0.7.0). Registered in PLUGIN_TABLE_OWNERS (ADR-008); its
0001 baseline really creates the tables.

P1a model: one wide manifestentries table + entrytype discriminator (not STI,
not JSON blob), manifestscopes (UNIQUE scopename+phase), the three multi-value
filter child tables, inusechecks + processes, immutable manifestpublishedversions
(frozen rendered JSON), manifestpayloads (inline, capped), pctypealiases
(mirror of the engine lib's alias graph). regvalue stored as its raw JSON
literal so DWord typing survives.

P1c importer + exporter: parse common + gea-shopfloor-* + preinstall.json into
draft rows and rebuild the JSON verbatim from rows in sortorder.

P1d parity harness (GATE A): filters.py mirrors the engine's four filter
functions + alias graph; parity.py proves import+export is behaviorally lossless
(field-identical + same-entries-fire across 18 machine-profile fixtures) WITHOUT
byte-diffing. Verified PASS against all 11 real reference manifests (64 entries)
and a synthetic site-neutral fixture covering every type/filter (the CI gate).

First slice (gea-shopfloor-cmm shape): service layer (import/publish/rollback/
export-to-share), CLI (parity, import-share, publish, export-share), and the
client endpoint GET /api/geenforce/manifest serving the current published
snapshot (never the draft) with ETag/304. Split permissions
geenforce.manage/publish/fetch. Tests prove import->publish->serve, draft edits
never change served bytes, publish+rollback, and auth (401 unauth/wrong-scope).

Contract 0.11.0: added service_token_authorized(scope) to shopdb.api so plugin
service endpoints authorize a scoped managed token without importing core token
internals. Documented in PLUGIN-HOOKS.md.
