Ack 1.1.0

Ack 1.1.0

Ack 1.1.0 is a correctness-focused release that aligns runtime validation,
generated schemas, and tooling with their documented contracts. It does not
change the public Dart API surface.

Validation and schema fixes

• Keep safeParse non-throwing for recoverable callback exceptions while
  preserving Dart Error values so programming defects remain visible.
• Bound direct, indirect, and wrapper-mediated lazy-schema recursion.
• Decode RFC 3339 date-times that use lowercase t and z separators.
• Validate multipleOf, IPv6, RFC 3339 date-times, range bounds, collection
  limits, unions, and enum definitions consistently with JSON Schema.
• Snapshot factory collections and correct schema/deep-collection equality.
• Preserve conflicting JSON Schema keywords through allOf, and export exact
  list/object sizes with the correct Draft-7 keywords.

Generator and tooling

• Reject nullable list element schemas during generation, matching Ack's
  runtime list contract.
• Use current source_gen diagnostics without undeclared debug-file output.
• Add stable full-output generator coverage.
• Make API checks, changelog updates, workspace setup, and root test orchestration
  fail truthfully instead of producing false-green results.

Behavior changes and migration notes

Although the public API is unchanged, invalid or ambiguous inputs that were
previously accepted may now fail earlier:

• Fix invalid schema definitions reported by construction-time ArgumentErrors.
• Put list nullability on the list (Ack.list(item).nullable()), not its item.
• Treat accumulated floating-point sums deliberately: round first or validate
  integer minor units such as cents before applying multipleOf.
• Refresh snapshots that assert the exact output of toJsonSchema().
• Expect AckException from parse() when a recoverable constraint or
  refinement callback throws; inspect the underlying cause for diagnostics.

See the package changelogs for the complete behavior notes.
