Dependency hardening: pin minimum safe dependency versions

[hamizan-azman]

Hi, thanks for AppAgent. Low-priority dependency-hardening note, not an active vulnerability report - a default install resolves to safe versions today.

This declaration also permits older versions with known CVEs. Pinning a minimum prevents an accidental downgrade (please test compatibility).

• requests: pin >= 2.32.0 (e.g. CVE-2014-1830 and 4 more)

(Low-priority dependency-hygiene note - feel free to close if not useful, happy to send a PR.)
