docs: document /personality none|default|neutral reset across personality docs

The reset keywords have existed in both CLI and gateway handlers since
June but were undocumented — users couldn't find how to cancel a
personality overlay. Adds a 'Resetting to the default' section to the
personality feature page and mentions the reset in the CLI guide,
slash-command reference (both tables), and messaging command table.

Flags: `--global` persists the change to config.yaml; `--session` forces session-only; `--once` applies to the next turn only; `--refresh` re-fetches the provider's model list; `--provider <name>` switches backend (session-only unless `--global`). A plain `/model <name>` is session-only unless `model.persist_switch_by_default: true` is set. **Note:** `/model` can only switch between already-configured providers. To add a new provider, exit the session and run `hermes model` from your terminal. **Cost note:** switching models mid-conversation resets the prompt cache — the cache key includes the model, so your next turn re-reads the entire conversation at full input price instead of the ~75%-discounted cached rate. Expected and unavoidable, but worth knowing on long sessions. |

 | `/focus [on\|off\|status]` | Toggle **focus view** — a display-only reduced-output mode showing just your prompt and the final response. Composes with `/verbose`: turning it on snaps tool progress to `off` and remembers your previous mode, and `/focus off` restores it. Each turn ends with a dim recovery line (`⋯ 7 tool lines hidden · /focus off to show`) and a persistent `◉ focus` badge sits in the status bar so you always know you're in the reduced view. Nothing is sent differently to the model — detail is hidden, never discarded. |
