mcp: P&L by class no longer counts closing entries; oracle tests for every tool's output
profit_and_loss_by_class re-added every posted entry in the range,
closing entries included: after closing January, its by-class P&L for
January showed an unclassified row of the whole period's net income,
negated. Closing entries are left out, as profit_and_loss_for_period
leaves them out.

tests/oracle_mcp.rs (24 tests): every export (CSV, JSON, XLSX, PDF,
IIF) against ledger-core's reports on the same books; the CPA package's
contents; P&L by class; the 1099 worksheet; disposals; depreciation;
payroll remittance; the digest against the journal; books.show's viewer
commands; resources; receipts and documents round-tripping; the 25 MiB
upload limit; bank import sides; reference resolution; partial FX lines;
preview balances. Written against the mutation run's 126 survivors.

//! Oracle tests for `ledger-mcp`, driven over stdio against the real binary.
//!
//! Every number a tool reports is checked against what `ledger-core` (or
//! `ledger-store`) computes for the same books, computed here from their
//! public APIs, or against first principles of double entry. Formats are
//! checked by reading them back: CSV is parsed (RFC 4180) to the same rows,
//! JSON deserializes, zips and XLSX unzip, IIF splits into its records.
//!
//! The books are mostly built in-process with [`Store`] (fast, and the
//! oracle sees exactly the books the server will open), then the store is
//! closed and the server started on the same data directory.
