feat(websearch): dynamic hook timeout from config + grok-code default

- Hook timeout now computed from max provider timeout + 30s buffer
- Removes hardcoded HOOK_TIMEOUT_SECONDS constant
- ensureHookConfig() now updates timeout when it changes
- Default OpenCode model changed from gpt-5-nano to grok-code
- Default OpenCode timeout changed from 60s to 90s
- Single source of truth: config.yaml controls all timeouts
