niwaki v1.1.0

The observation / query surface — which 1.0.0 declared still-evolving — gets
its read foundation: the full APIC query grammar, expressed as a fluent, typed
API and validated against a live controller. The configuration API (design
DSL, push modes) is unchanged and remains stable; the breaking changes below are
confined to reading.

Added

• Filter operators. anybit, allbit (emulated as and_(anybit, …)),
  xor and raw join eq/ne/lt/le/gt/ge/bw/wcard and
  and_/or_/not_. anybit closes the write-but-not-filter gap on bitmask
  (Flags) fields — you can now filter "where this flag is set".
• Smart values in where(...). A list or tuple means membership, a * in a
  string means wildcard, a set stays bitmask equality; explicit wrappers
  any_of(...), like(pattern) and between(start, end) remove any ambiguity.
• Response shaping — full GET grammar. self_only(), also(...),
  subtree_full(), and include_subtree(...) with the SubtreeInclude facets
  (faults, health, stats, audit/event/fault/health records, tasks, count, …);
  multi-key order_by.
• Executors and Python protocols. A query is a lazy iterable
  (for mo in q, list(q)); q[:n] sets a server-side limit; .one() and
  .exists(); execute_raw(). count() and exists() honor the limit. New
  typed NoResultError / MultipleResultsError.
• Uniform result access on every object, generated model or operational
  class alike: .dn, mo["wireName"], and .attrs (the full wire view).

Changed

• with_faults() no longer filters. It embeds faults on each object without
  restricting the result; chain only_faulted() to return only faulted objects.
  (Previously with_faults() implicitly restricted to faulted objects.)
• bool(query) / if query: now raises TypeError. A query is lazy, so
  truthiness would hide a network call — use .exists().
• subtree_where(prop=value) qualifies the property with the included subtree
  class. include(fvSubnet).subtree_where(scope=...) filters fvSubnet.scope,
  not the queried class; when several classes are included, pass an explicitly
  qualified expression (subtree_where(eq("fvSubnet.scope", …))).

Removed

• contains() and isdigit() filter operators — the APIC has no such filter
  types (verified on 6.0(9c)). Use like("*x*") (subject to the property's
  format) or raw(...).
