SimplyBased 0.1.0 — Couchbase-native ActiveModel ORM

A from-scratch fork of simply_couch's model layer that runs on Couchbase
natively: `include SimplyBased::Model` instead of `include SimplyCouch::Model`.

- SimplyBased::Store replaces the CouchDB layer: KV documents, N1QL/SQL++
  finders + lazily-created GSIs, CAS mapped onto _rev. No design documents or
  JavaScript map/reduce — the hand-written association views become N1QL
  (belongs_to/has_many/has_one scalar FK; habtm via ANY ... SATISFIES + array
  index, or KV multi-get on the storing side).
- Redis replacements on the same cluster: Counter (atomic increment/decrement),
  Cache (ActiveSupport::Cache::Store over KV+TTL, drop-in Rails.cache/ActiveJob),
  Lock (insert-if-absent + TTL + CAS-checked release).
- Runs the simply_couch test suite against live Couchbase: 378/432 applicable
  examples green (CouchDB-mechanic specs tagged :couchdb_only and excluded).
- Remaining: ancestry (tree) + embedded_in reverse-lookups (recursive/embedded
  N1QL) and a few pagination/lifecycle edges.
