Introduces optional-plugins/ — a new category for plugins that ship with the repo but are NOT auto-discovered. They live alongside the code but only land in ~/.hermes/plugins/ (and thus get loaded) when the user explicitly installs them. Core changes: - optional-plugins/observability/langfuse-tracing/ — langfuse tracing plugin (pre/post LLM + tool hooks, usage/cost normalization, fail-open when SDK missing). NOT in plugins/ so zero import overhead on devices that don't want it. - hermes_cli/plugins_cmd.py — official install path: _resolve_official_plugin() recognises 'official/<category>/<name>' identifiers and copies from optional-plugins/ into ~/.hermes/plugins/ (no git clone, no network). _list_official_plugins() enumerates available optional plugins. cmd_list(available=True) shows not-yet-installed official plugins. - hermes_cli/main.py — hermes plugins list --available flag - hermes_cli/tools_config.py — Langfuse Observability in TOOL_CATEGORIES; post_setup handler installs the langfuse SDK and runs cmd_install() - hermes_cli/config.py — Langfuse credentials in OPTIONAL_ENV_VARS; optional tuning keys in _EXTRA_ENV_KEYS User flows: hermes plugins install official/observability/langfuse-tracing hermes plugins list --available hermes tools (-> Langfuse Observability -> credentials -> auto-installs) Closes #15764
