btctax-core 0.3.0

Offline US Bitcoin tax engine — per-lot cost basis, realized gains, and IRS-form projection (part of btctax).
Documentation
//! btctax-core: domain model + pure deterministic event-sourced projection for the bitcoin_tax ledger.
//! The projection (`project`) is total and never panics (spec §7.1); only `persistence` performs I/O.
