feat: v2.1.0 — mass-panic mode with incremental assemblyline + verisimdb persistence

Wire up BLAKE3 incremental scanning to assemblyline CLI:
- --incremental flag skips repos unchanged since last run
- --cache flag for custom fingerprint cache location
- Fingerprint cache auto-saved/loaded between runs

Wire verisimdb persistence into assemblyline:
- --store flag now works with assemblyline (was only assail/assault)
- Aggregate assemblyline reports stored as verisimdb hexads
- New persist_assemblyline_report() with assemblyline-specific hexad builder

Document three deployment modes:
- Standalone: single binary, zero deps, USB/air-gapped
- Panicbot: automated CI via gitbot-fleet, JSON contract PA001-PA020
- Mass-panic: assemblyline + incremental + verisimdb + delta + notify + Chapel (planned)

Fix pre-existing test failures:
- Add migration_metrics: None to all AssailReport test fixtures (7 files)
- Add cache_file: None to all AssemblylineConfig test fixtures

269 tests pass, 0 failures.

+## Deployment Modes
+
+Three self-contained modes — none requires the others:
+
+1. **Standalone** (USB/laptop/air-gapped): Single binary, zero deps, `assail`/`assault` individual targets
+2. **Panicbot** (gitbot-fleet/CI): Automated JSON scanning, PA001–PA020 codes, bot directives
+3. **Mass-panic** (assemblyline + verisimdb + Chapel): Org-scale batch scanning with incremental BLAKE3, hexad persistence, delta reporting, notifications. Chapel (planned) for distributed multi-machine orchestration.

 ## Planned Features (Next Priorities)
 
-1. **verisimdb API integration**: Push scan results as hexads directly
-2. **Incremental assemblyline**: BLAKE3 delta scanning (skip unchanged repos)
-3. **kanren context-facts**: ~10 rules for FP suppression (~8% -> ~2-3%)
-4. **hypatia pipeline**: Export kanren facts as Logtalk predicates via PanLL
-5. **Shell completions**: bash, zsh, fish, nushell
+1. **verisimdb HTTP API integration**: Push hexads via REST (awaiting API stabilisation)

+## Deployment Modes
+
+panic-attack supports three deployment modes. Each is self-contained — none requires the others.
+
+### Standalone (USB / laptop / air-gapped)
+
+**Use case:** Quick security scan of a single project. No dependencies, no network, no database. Just the binary.
+
+```bash
+# Copy the binary to a USB stick, run it anywhere
+panic-attack assail /path/to/project
+panic-attack assault /path/to/project --output report.json
+```
+
+- Single static binary (~15MB, stripped)
+- Zero runtime dependencies
+- Works offline, air-gapped, on any Linux machine
+- Full 47-language analysis + 20 weak point categories
+- JSON/YAML/SARIF output for manual review
+
+### Panicbot (gitbot-fleet / CI)
+
+**Use case:** Automated scanning in CI pipelines or via gitbot-fleet's panicbot verifier.
+
+```bash
+# panicbot invokes this in CI:
+panic-attack assail /path/to/repo --output-format json --quiet
+```
+
+- Invoked by panicbot (gitbot-fleet verifier bot)
+- JSON contract: findings mapped to PA001–PA020 codes
+- Bot directives at `.machine_readable/bot_directives/panicbot.scm`
+- Safe allow list (assail, adjudicate, diagnostics) — no stress testing in CI
+- Diagnostics endpoint for hypatia/gitbot-fleet health checks
+- No verisimdb or Chapel required
+
+### Mass-panic (assemblyline + verisimdb + Chapel)
+
+**Use case:** Organisation-scale or datacenter-scale scanning across hundreds/thousands of repos with persistence, trending, and delta reporting.
+
+```bash
+# Scan everything with incremental caching + verisimdb persistence
+panic-attack assemblyline /path/to/all/repos/ --incremental --store ./verisimdb-data/
+
+# Compare runs
+panic-attack diff
+
+# Generate notifications for critical findings
+panic-attack notify sweep-report.json --critical-only --github-issues
+```
+
+- **Assemblyline**: Batch scan with rayon parallelism (17.7x speedup)
+- **BLAKE3 incremental**: Skip unchanged repos between runs
+- **VerisimDB hexads**: Persist results for trending and cross-project analysis
+- **Delta reporting**: Track what's new/fixed since last run
+- **Notification pipeline**: Markdown summaries + GitHub issue creation
+- **Chapel metalayer** (planned): Distributed multi-machine orchestration via `coforall`
+- **PanLL Panel-W**: Visual triage dashboard for findings
+
+None of these components are required by the standalone or panicbot modes.
