/**
 * Integration coverage for the `runFullAnalysis` incremental-orchestration
 * wiring (Claude PR-review Finding 2).
 *
 * These tests exercise the *real runtime path* — they call
 * `runFullAnalysis` against a real on-disk git repo backed by a real
 * LadybugDB at `<repo>/.gitnexus/`, and assert behaviours that pure
 * unit tests on `diffFileHashes` / `extractChangedSubgraph` cannot
 * catch:
 *
 *   - the `isIncremental` decision (post-pipeline eligibility check)
 *   - `incrementalInProgress` dirty-flag set-before-mutation and
 *     clear-on-success
 *   - the importer-closure expansion (1-hop reached via the writable
 *     set, transitive reachable via bounded BFS)
 *   - the "forced full rebuild on dirty-flag-from-prior-crash" path
 *
 * Each test creates a temporary git repo, runs the analyzer, and asserts
 * on the resulting `meta.json` and graph state. Cleanup is best-effort
 * (Windows LadybugDB handle release can lag; `cleanupTempDir` retries).
