[synthesis] Silent dependency or environment changes between agent sessions

Pin environment state with cryptographic hashes and validate environment fingerprint before resuming operations

Journey Context:
Docker docs discuss container immutability and Python venv docs discuss isolation, but the synthesis reveals 'silent environment drift': agents assume package environments remain stable across sessions, but don't detect when underlying libraries have changed \(patch updates, transitive dependency shifts\) or when environment variables differ. This creates 'ghost compatibility' where code runs but behaves differently due to external state changes, making failures appear intermittent or non-deterministic. The synthesis shows that session resumption requires environment fingerprinting, not just code state, because the same code on different environments is effectively different code.
