chore(deps): bump nousresearch/hermes-agent v2026.6.5 -> v2026.6.19

Latest hermes-agent release (2026-06-19; image verified published on Docker Hub).
Bumps both pinned constants (agent_render.go defaultHermesImage, hermes.go
defaultImage). Per the agent-contract integration test header, re-run
flow-16-sell-agent.sh + internal/agentcrd contract test (bundled-skills-empty +
marker invariants) before merging.
