docs: complete Daytona backend documentation coverage

Update all remaining files that enumerate terminal backends to include
Daytona. Covers security docs (bypass info, backend comparison table),
environment variables reference (DAYTONA_API_KEY, TERMINAL_DAYTONA_IMAGE,
container resources header), AGENTS.md (architecture tree, config keys),
environments/README.md, hermes_base_env.py field description, and various
module docstrings.

Follow-up to PR #451 merge.
