docs: update README and add help-chat, deduplication docs

README.md:
- Add DAST, pentesting, code graph, AI chat, MCP, help chat to features table
- Add Gitea to tracker list, multi-language LLM triage note
- Update architecture diagram with all 5 workspace crates
- Add new API endpoints (graph, DAST, chat, help, pentest)
- Update dashboard pages table (remove Settings, add 6 new pages)
- Update project structure with new directories
- Add Keycloak, Chromium to external services

New docs:
- docs/features/help-chat.md — Help chat assistant usage, API, config
- docs/features/deduplication.md — Finding dedup across SAST, DAST, PR, issues

Updated:
- docs/features/overview.md — Add help chat section, update tracker list

 ## About
 
-Compliance Scanner is an autonomous agent that continuously monitors git repositories for security vulnerabilities, GDPR/OAuth compliance patterns, and dependency risks. It creates issues in external trackers (GitHub/GitLab/Jira) with evidence and remediation suggestions, reviews pull requests, and exposes a Dioxus-based dashboard for visualization.
+Compliance Scanner is an autonomous agent that continuously monitors git repositories for security vulnerabilities, GDPR/OAuth compliance patterns, and dependency risks. It creates issues in external trackers (GitHub/GitLab/Jira/Gitea) with evidence and remediation suggestions, reviews pull requests with multi-pass LLM analysis, runs autonomous penetration tests, and exposes a Dioxus-based dashboard for visualization.
 
-> **How it works:** The agent runs as a lazy daemon -- it only scans when new commits are detected, triggered by cron schedules or webhooks. LLM-powered triage filters out false positives and generates actionable remediation.

+# Finding Deduplication
+
+The Compliance Scanner automatically deduplicates findings across all scanning surfaces to prevent noise and duplicate issues.
+
+## SAST Finding Dedup
+
+Static analysis findings are deduplicated using SHA-256 fingerprints computed from:
+
+- Repository ID
+- Scanner rule ID (e.g., Semgrep check ID)
+- File path
+- Line number
+
+Before inserting a new finding, the pipeline checks if a finding with the same fingerprint already exists. If it does, the finding is skipped.
+
+## DAST / Pentest Finding Dedup
+
+Dynamic testing findings go through two-phase deduplication:
+
+### Phase 1: Exact Dedup
+
+Findings with the same canonicalized title, endpoint, and HTTP method are merged. Evidence from duplicate findings is combined into a single finding, keeping the highest severity.
+
+**Title canonicalization** handles common variations:
+- Domain names and URLs are stripped from titles (e.g., "Missing HSTS header for example.com" becomes "Missing HSTS header")
+- Known synonyms are resolved (e.g., "HSTS" maps to "strict-transport-security", "CSP" maps to "content-security-policy")
+
+### Phase 2: CWE-Based Dedup
+
+After exact dedup, findings with the same CWE and endpoint are merged. This catches cases where different tools report the same underlying issue with different titles or vulnerability types (e.g., a missing HSTS header reported as both `security_header_missing` and `tls_misconfiguration`).
+
+The primary finding is selected by highest severity, then most evidence, then longest description. Evidence from merged findings is preserved.
+
+### When Dedup Applies
+
+- **At insertion time**: During a pentest session, before each finding is stored in MongoDB
+- **At report export**: When generating a pentest report, all session findings are deduplicated before rendering
+
+## PR Review Comment Dedup
+
+PR review comments are deduplicated to prevent posting the same finding multiple times:
+
+- Each comment includes a fingerprint computed from the repository, PR number, file path, line, and finding title
+- Within a single review run, duplicate findings are skipped
+- The fingerprint is embedded as an HTML comment in the review body for future cross-run dedup
+
+## Issue Tracker Dedup
+
+Before creating an issue in GitHub, GitLab, Jira, or Gitea, the scanner:
+
+1. Searches for an existing issue matching the finding's fingerprint
+2. Falls back to searching by issue title
+3. Skips creation if a match is found
+
+## Code Review Dedup
+
+Multi-pass LLM code reviews (logic, security, convention, complexity) are deduplicated across passes using proximity-aware keys:
+
+- Findings within 3 lines of each other on the same file with similar normalized titles are considered duplicates
+- The finding with the highest severity is kept
+- CWE information is merged from duplicates

+# Help Chat Assistant
+
+The Help Chat is a floating assistant available on every page of the dashboard. It answers questions about the Compliance Scanner using the project documentation as its knowledge base.
+
+## How It Works
+
+1. Click the **?** button in the bottom-right corner of any page
+2. Type your question and press Enter
+3. The assistant responds with answers grounded in the project documentation
+
+The chat supports multi-turn conversations -- you can ask follow-up questions and the assistant will remember the context of your conversation.
+
+## What You Can Ask
+
+- **Getting started**: "How do I add a repository?" / "How do I trigger a scan?"
+- **Features**: "What is SBOM?" / "How does the code knowledge graph work?"
+- **Configuration**: "How do I set up webhooks?" / "What environment variables are needed?"
+- **Scanning**: "What does the scan pipeline do?" / "How does LLM triage work?"
+- **DAST & Pentesting**: "How do I run a pentest?" / "What DAST tools are available?"
+- **Integrations**: "How do I connect to GitHub?" / "What is MCP?"
+
+## Technical Details
+
+The help chat loads all project documentation (README, guides, feature docs, reference) at startup and caches them in memory. When you ask a question, it sends your message along with the full documentation context to the LLM via LiteLLM, which generates a grounded response.
+
+### API Endpoint
+
+```
+POST /api/v1/help/chat
+Content-Type: application/json
+
+{
+  "message": "How do I add a repository?",
+  "history": [
+    { "role": "user", "content": "previous question" },
+    { "role": "assistant", "content": "previous answer" }
+  ]
+}
+```
+
+### Configuration
+
+The help chat uses the same LiteLLM configuration as other LLM features:
+
+| Environment Variable | Description | Default |
+|---------------------|-------------|---------|
+| `LITELLM_URL` | LiteLLM API base URL | `http://localhost:4000` |
+| `LITELLM_MODEL` | Model for chat responses | `gpt-4o` |
+| `LITELLM_API_KEY` | API key (optional) | -- |
+
+### Documentation Sources
+
+The assistant indexes the following documentation at startup:
+
+- `README.md` -- Project overview and quick start
+- `docs/guide/` -- Getting started, repositories, findings, SBOM, scanning, issues, webhooks
+- `docs/features/` -- AI Chat, DAST, Code Graph, MCP Server, Pentesting, Help Chat
+- `docs/reference/` -- Glossary, tools reference
+
+If documentation files are not found at startup (e.g., in a minimal Docker deployment), the assistant falls back to general knowledge about the project.
