 * Unstuck settings schema (2 fields), rendered via the `/unstuck:settings`

 *
 * - `searchTimeoutMs`: timeout applied to search tools — the `find`/`grep`
 *   tools (watchdog abort) and search bash commands (native bash `timeout`).
 * - `bashTimeoutMs`: timeout applied to ANY bash command. For a search bash
 *   command, the SHORTER of the two takes effect.
 *
 * Both are `duration` settings: `null` means Infinite (no limit). Values are
 * stored in milliseconds (settings-ui convention); the bash tool's native
 * `timeout` input field expects seconds, so conversion happens at the injection
 * site (see src/search-timeout.ts).
