insIGht v0.2.0-preview.3

This unsigned preview improves large-export responsiveness, archive hardening,
report safety, and release reproducibility while preserving the offline product
boundary.

• Load relationship and adjacent-snapshot change results incrementally with
  debounced native search.
• Compute summaries with bounded-memory SQL and stream CSV/JSON reports from a
  transaction-consistent database snapshot.
• Write reports through private temporary files and atomically replace the
  selected destination only after a successful flush and sync.
• Reject oversized or malformed ZIP/ZIP64 metadata, excessive compressed work,
  duplicate canonical paths, unsafe paths, and excessive relationship records.
• Use one pinned Rust workspace, toolchain, and lockfile across the desktop,
  Fame core, and synthetic lab.
• Gate release packaging on the complete build, frontend test, Rust format,
  strict Clippy, locked Rust test, dependency-audit, and synthetic-lab checks.
• Validate the import and SQLite persistence path against a private real export;
  no private fixture or account data is included in this release.

Fame networking, retrieval, and ranking remain unavailable. The app contains no
Instagram login, scraping, credential, PIR, mixnet, telemetry, or fallback
network path.

Artifacts are unsigned. Verify downloads using the attached SHA256SUMS file.
