v0.1.0

Initial release.

Added

• An SQL-semantics mutation catalog for the Ecto surface, independent of
  Mutare's Elixir-semantics built-ins: every mutation is one a real SQL engine
  will run, and equivalence reasoning follows SQL's three-valued logic.
• In-condition families (delivered through ^/dynamic injection so the
  query still compiles once): comparison, null_predicate, connective,
  membership, arithmetic, coalesce, temporal, integer_literal,
  float_literal, the opt-in string_literal/atom_literal/boolean_literal
  arms, binding_reorder, and filter_drop.
• Query-shape families: ordering, ordering_nulls, bound, join_type,
  combination, aggregate, clause_drop, and query_terminal.
• Repo-write and changeset families: persistence, on_conflict,
  validation_drop, and hook_drop.
• Both query syntaxes — the from keyword form (piped too) and the
  composable pipe form — across direct, aliased, and import/use-bundled
  call styles; schema definitions are left untouched.
• Configuration per {Mutare.Ecto, …} entry: repo: (Repo-call
  recognition — one module or a list), families: (:default, :all, an explicit list, or
  {base, except: […]}), dialects: (portable core by default; :postgres /
  :mysql gate dialect-specific swaps), and as: report renaming.
• Equivalence reporting: boundary/NULL-sensitive families annotate each
  survivor with the specific fixture data a kill would need
  (Mutare.Ecto.equivalence_sensitive_families/0).
• Structural-position safety: literals that shape the SQL (fragment
  templates, interval units, cast types, field/binding names) are never
  mutated, so no mutant can poison the single metamutant build.
