Instead of launching heavy browser binaries for static or server-rendered web workflows, BrowserBridge fetches HTML over `httpx`, distills interactive elements into compact `@node` trees, tracks stateful form/click transitions per session, and records append-only SHA-256 DOM hash chains in SQLite. ## Features - **HTTP Navigation with Redirect SSRF Guard**: Validates initial and redirect URLs against loopback, RFC1918 private networks, and cloud metadata (`169.254.169.254`). - **Accessibility Object Model (AOM) Extraction**: Condenses `<button>`, `<a href>`, and `<input>` elements into compact `@node-N` descriptors. - **Clean Text Extraction**: Strips `<script>`, `<style>`, `<svg>`, and markup noise into readable plain text. - **SHA-256 Durable Action Receipts**: Every `navigate_page`, `click_element`, and `fill_form_field` call records `pre_state_hash` and `post_state_hash` transitions in SQLite (`~/.browserbridge/receipts.db`, `0600`) for audit verification via `ve…
