docs: fix all remaining minor accuracy issues

- updating.md: Note that 'hermes update' auto-handles config migration
- cli.md: Add summary_model to compression config, fix display config
  (add personality/compact), remove unverified pastes/ claim
- configuration.md: Add 5 missing config sections (stt, human_delay,
  code_execution, delegation, clarify), fix display defaults,
  fix reasoning_effort default to empty/unset
- messaging/index.md: Add GATEWAY_ALLOWED_USERS to security section
- skills.md: Add category field to skills_list return value
- mcp.md: Document auto-registered utility tools (resources/prompts)
- architecture.md: Fix file_tools.py reference, base_url default to None,
  synchronous agent loop pseudocode
- cli-commands.md: Fix hermes logout description
- environment-variables.md: Add HERMES_QUIET, HERMES_EXEC_ASK,

-Higher reasoning effort gives better results on complex tasks at the cost of more tokens and latency.
+When unset (default), the model's own default reasoning level is used. Setting a value overrides it — higher reasoning effort gives better results on complex tasks at the cost of more tokens and latency.

+```yaml
+human_delay:
+  mode: "off"                  # off | natural | custom

+Configure the sandboxed Python code execution tool:
+
+```yaml
+code_execution:
+  timeout: 300                 # Max execution time in seconds
+  max_tool_calls: 50           # Max tool calls within code execution
+```
+
+## Delegation
+
+Configure subagent behavior for the delegate tool:
+
+```yaml
+delegation:
+  max_iterations: 50           # Max iterations per subagent
+  default_toolsets:             # Toolsets available to subagents

+
+## Clarify

+```yaml
+clarify:
+  timeout: 120                 # Seconds to wait for user clarification response
+```
