atomwrite 0.1.12

//! Batch 4 regression tests for v0.1.12 — gap categories not covered in previous batches.
//!
//! Categories covered (12 total):
//!   1. `--json-schema` for the 6 new subcommands
//!   2. `recover_orphan_journals` end-to-end (3 cases)
//!   3. `case --subvert` boundary (0, 1, 2, malformed)
//!   4. G72 syntax check on a > 1 MiB stream (chunked internally)
//!   5. `query --threads 1` and `outline --threads 1`
//!   6. Shell-completion generation (bash + zsh + fish) for query/outline
//!   7. Locale pt-BR via `LANG=pt_BR.UTF-8` for `set`/`get`/`del`
//!   8. `LANG=C` (POSIX) for `set` (no UTF-8 expected to fail)
//!   9. `--max-filesize 1` edge case for `query`
//!  10. `recover_orphan_journals` on empty dir
//!  11. `recover_orphan_journals` on dir with valid Committed journals (no orphans)
//!  12. `set --format toml` explicit format flag (default-detection path)
