/**
 * /exit and /clear session commands.
 *
 * Own code (not vendored): moved in from the owner's personal Pi config
 * (`~/.pi/agent/extensions/exit-command.ts` + `clear-as-new.ts`, 2026-07-20).
 * /clear replaces the npm package `pi-clear` (which also reloaded the runtime).
 *
 * Registration-time gate (`sessionCommandsEnabled`, default on): commands
 * cannot be unregistered live, so toggling requires /reload — same contract
 * as `imagePasterEnabled` and `spinnerEnabled`.
