…ony bot Mirrors the Java BDK's bdk-ai-agent-example: any message addressed to the bot is forwarded to a LangGraph ReAct agent backed by Gemini, with BDK-backed tools for user lookup, room member listing, and sending messages.
Harden workflows against supply-chain tag mutation by pinning actions to SHAs, bump cryptography to >=48.0.1 for a CVE fix, allow BSD-3-Clause license, and add a documented safety-policy exception for CVE 96886 (fix requires urllib3 2.7.0 which drops Python 3.9 support).
Semgrep flagged mutable actions/upload-artifact@v4 tag; safety flagged aiohttp 3.13.5 CVEs because cve-scanning-python.yml was missing the -i ignore flags already present in security.yml for py3.9-only findings.
