[Unreleased]

allow_splits: true option on ExReconcile.reconcile/3 enables many-to-one matching after the standard 1:1 pass. A single transaction on one side can now be matched against a group of two or more transactions on the other side whose amounts sum to it (within amount_tolerance). Results are stored in result.splits as ExReconcile.Result.split_match() tuples and are excluded from unmatched_left / unmatched_right.
ExReconcile.Result.split_match/0 type — {Transaction.t(), [Transaction.t()]} for a left-anchor split and {[Transaction.t()], Transaction.t()} for a right-anchor split.
splits field on %ExReconcile.Result{} (defaults to []).
splits key in ExReconcile.Result.summary/1; total_left and total_right counts now include transactions covered by split groups.
Splits line in the ExReconcile.format/2 text report header and a == Splits == section listing each group with its [1:N] or [N:1] ratio.

ExReconcile.Transaction struct with new/1 and label/1 helpers.
ExReconcile.Config with validation for match_on, amount_tolerance, date_tolerance, and description_match options.
ExReconcile.reconcile/3 - greedy bipartite matching engine with configurable field-level tolerances.
ExReconcile.Result with summary/1 and clean?/1 helpers.
ExReconcile.format/2 - human-readable text diff report.
Full ExUnit test suite.
