feat: interactive network map, IOC highlighting, AUP hunt selector, type filters

- NetworkMap: hunt-scoped force-directed graph with click-to-inspect popover
- NetworkMap: zoom/pan (wheel, drag, buttons), viewport transform
- NetworkMap: clickable IP/Host/Domain/URL legend chips to filter node types
- NetworkMap: brighter colors, 20% smaller nodes
- DatasetViewer: IOC columns highlighted with colored headers + cell tinting
- AUPScanner: hunt dropdown replacing dataset checkboxes, auto-select all
- Rename 'Social Media (Personal)' theme to 'Social Media' with DB migration
- Fix /api/hunts timeout: Dataset.rows lazy='noload' (was selectin cascade)
- Add OS column mapping to normalizer
- Full backend services, DB models, alembic migrations, new routes
- New components: Dashboard, HuntManager, FileUpload, NetworkMap, etc.
- Docker Compose deployment with nginx reverse proxy

+# Performance Profiling (Bun/Node)
+
+Use this skill when:
+- a hot path feels slow
+- CPU usage is high
+- you suspect accidental O(n²) or repeated work
+- you need evidence before optimizing
+
+## Bun CPU profiling
+Bun supports CPU profiling via `--cpu-prof` (generates a `.cpuprofile` you can open in Chrome DevTools).
+
+Upcoming: `bun --cpu-prof-md <script>` outputs a CPU profile as **Markdown** so LLMs can read/grep it easily.
+
+### Workflow (Bun)
+1) Run the workload with profiling enabled
+   - Today: `bun --cpu-prof ./path/to/script.ts`
+   - Upcoming: `bun --cpu-prof-md ./path/to/script.ts`
+2) Save the output (or `.cpuprofile`) into `./profiles/` with a timestamp.
+3) Ask the Reviewer agent to:
+   - identify the top 5 hottest functions
+   - propose the smallest fix
+   - add a regression test or benchmark
+
+## Node CPU profiling (fallback)
+- `node --cpu-prof ./script.js` writes a `.cpuprofile` file.
+- Open in Chrome DevTools → Performance → Load profile.
+
+## Rules
+- Optimize based on measured hotspots, not vibes.
+- Prefer algorithmic wins (remove repeated work) over micro-optimizations.
+- Keep profiling artifacts out of git unless explicitly needed (use `.gitignore`).
