LoggingCfg gains two fields with serde defaults: keep_recent_runs
(default 100, top-N file retention) and retention_days (default 30,
time-based retention for both ndjson files and the SQLite mirror).
IngestLogWriter::open now runs cleanup_old_logs before creating a new
ingest-*.ndjson — delete iff (idx >= keep_recent) OR (modified <=
cutoff). ingest_with_config_opts also calls
SqliteStore::prune_pdf_ocr_events(retention_days) at ingest start so
the SQLite mirror tracks the same retention window.
Backward compat (AC-9): both new fields use #[serde(default = ...)],
so a pre-v0.20.x config with only [logging] ingest_log_enabled +
ingest_log_dir parses unchanged. kebab init writes the new defaults
automatically via Config::default() -> toml::to_string_pretty (AC-12).
docs/SMOKE.md config example synced.
Closure r1 F5: explicit OR-on-stale comment inside cleanup_old_logs.

v0.20.x ingest log surface 의 config side. LoggingCfg struct 신설:
* ingest_log_enabled (bool, default true)
* ingest_log_dir (PathBuf, default "{state_dir}/logs")
#[serde(default)] tag 로 pre-v0.20 config 가 [logging] section 부재
시 LoggingCfg::default() 자동 init (AC-10 backward compat).
{state_dir} placeholder 의 실제 expand 는 step 2 (IngestLogWriter)
의 expand_log_dir helper 가 담당 (kebab-config 의 expand_path_with_base
는 {state_dir} 미지원, spec §6 R-3).
