Add docs directory tree with clickable links and key findings table

- EN README: tree view + summary table with EN doc links
- ZH README: tree view + summary table with bilingual links (EN + ZH)
- Both tables show topic, key findings, and clickable links per row

+| # | Topic | Key Findings |
+|---|-------|-------------|
+| 01 | **Telemetry & Privacy** | Two analytics sinks (1P → Anthropic, Datadog). Environment fingerprint, process metrics, repo hash on every event. **No UI-exposed opt-out** for 1st-party logging. `OTEL_LOG_TOOL_DETAILS=1` enables full tool input capture. |
+| 02 | **Hidden Features & Codenames** | Animal codenames (Capybara v8, Tengu, Fennec→Opus 4.6, **Numbat** next). Feature flags use random word pairs (`tengu_frond_boric`) to obscure purpose. Internal users get better prompts, verification agents, and effort anchors. Hidden commands: `/btw`, `/stickers`. |
+| 03 | **Undercover Mode** | Anthropic employees auto-enter undercover mode in public repos. Model instructed: *"Do not blow your cover"* — strip all AI attribution, write commits "as a human developer would." **No force-OFF exists.** Raises transparency questions for open-source communities. |
+| 04 | **Remote Control** | Hourly polling of `/api/claude_code/settings`. Dangerous changes show blocking dialog — **reject = app exits**. 6+ killswitches (bypass permissions, fast mode, voice mode, analytics sink). GrowthBook flags can change any user's behavior without consent. |
+| 05 | **Future Roadmap** | **Numbat** codename confirmed. Opus 4.7 / Sonnet 4.8 in development. **KAIROS** = fully autonomous agent mode with `<tick>` heartbeats, push notifications, PR subscriptions. Voice mode (push-to-talk) ready but gated. 17 unreleased tools found. |
