feat: v0.2.0 — HTML dashboard, plugin install, attention curve scorer, docs

- prism/dashboard.py: self-contained HTML dashboard at ~/.claude/prism/dashboard.html;
  auto-regenerated by prism analyze; prism dashboard command with --serve / --no-open
- prism/advisor.py: _recommend_attention_curve() flags critical CLAUDE.md rules buried
  in the LLM attention dead zone (middle 55% of file); RESTRUCTURE recommendation
- prism/cli.py: dashboard_cmd + auto-regenerate dashboard after analyze
- plugin.json + skills/prism-analyze/SKILL.md: Claude Code plugin (skills only, no hooks)
- assets/splash.svg: redesigned — larger prism, 6-colour refracted rays with glow layers
- assets/dashboard-preview.png + dashboard-detail.png: README screenshots from mock data
- docs/: how-it-works.md, claude-md-guide.md, commands.md, faq.md
- tests/test_dashboard.py: 15 new tests (96 total, all passing)
- Bump version 0.1.2 -> 0.2.0

+## Trust & Safety
+
+<details>
+<summary><b>Does PRISM send any data anywhere?</b></summary>
+
+No. PRISM never makes network calls. All analysis runs locally against files
+already on your machine. No telemetry, no analytics, no external servers.
+</details>
+
+<details>
+<summary><b>Can PRISM hurt my Claude Code sessions?</b></summary>
+
+No. PRISM is read-only — it never modifies session files. It reads
+`~/.claude/projects/` but never writes to it. Your sessions are completely
+untouched.
+</details>
+
+<details>
+<summary><b>Does PRISM modify my CLAUDE.md without asking?</b></summary>
+
+Only if you explicitly run `prism advise --apply` and confirm the prompt.
+`prism advise` (without --apply) only prints recommendations — it never
+touches any file.
+</details>
+
+<details>
+<summary><b>What data does PRISM read?</b></summary>
+
+Only the JSONL session files Claude Code writes to `~/.claude/projects/`
+and your CLAUDE.md files. It reads nothing else. No API keys, no environment
+variables, no network traffic.
+</details>
+
+<details>
+<summary><b>Does it work with Claude Code Max / Pro / Team?</b></summary>
+
+Yes — PRISM reads local session files which are written by all Claude Code
+subscription tiers. The analysis works identically regardless of your plan.
+</details>
+
+<details>
+<summary><b>What are PRISM's dependencies?</b></summary>
+
+Four packages: textual, rich, typer, watchdog. All well-maintained,
+widely-used Python libraries. No C extensions, no compiled binaries.
+</details>

 ## The CLAUDE.md re-read problem
 
 Every tool call Claude Code makes re-reads your CLAUDE.md from the top of the context. A 200-line CLAUDE.md × 50 tool calls = 10,000 tokens spent on instructions, per session. If your CLAUDE.md has grown to include personality instructions, full documentation copies, or rules that only apply to one subdirectory — you're paying for all of it every time.
