feat(m7.5b): TypeScript ORM adapter — fromDrizzle

[shamspias]

Auto-expose your Drizzle models as intent-level capabilities — the TS mirror of Go's GORM FromORM and Python's from_orm.

• reins/orm subpath (package.json exports + optional peerDependency drizzle-orm), so the core reins package never depends on an ORM.
• src/orm/build.ts: the ORM-neutral generation engine (ZERO deps) — a faithful port of Go's orm.go behind a Backend interface. Intent-level names, natural-key-over-id lookups (unique string preferred, hint-ranked), lean params, trimmed responses, a schema index, and gated writes; every generated capability must pass the linter or it is dropped. Another ORM means implementing only introspection + the six ops.
• src/orm/drizzle.ts: the Drizzle adapter. introspect() reflects a Drizzle table object via getTableColumns/getTableName (no database needed) into ORM-neutral ModelInfo (jsonType/nullable/autoincrement/hasDefault/unique); DrizzleBackend runs find/count/get/create/update/delete through Drizzle's query builder; fromDrizzle() wires it to buildCapabilities. Drizzle's db/table types are deeply generic, so they're treated structurally.
• tests: orm-build.test.ts drives the engine with a fake Backend (read/write generation, natural-key vs pk fallback, keyless models, required-column inference, handler dispatch, not-found errors, untrusted-arg filtering); orm-drizzle.test.ts covers introspection (no DB) and a full create/get/count/find/update/delete round-trip against in-memory libsql.

Verified: make js-check green — format, typecheck, 125 tests (124 pass, 1 skip); the reins/orm subpath builds and imports cleanly as ESM.
