release: v1.11.1

## Summary

- **Fix `isProcessing` tracking**: The `isProcessing` store field was initialised as `false` and never set to `true` in production, making all submission guards no-ops. Now `setProcessing(true)` is called after `send_prompt` succeeds in both `handleSubmit` and `handleQuickAction`, and `setProcessingForConversation(id, false)` is called when the backend emits an idle/success/error state.
- **Fix auto-granted tools dropped on permission reconnect** (closes #198): `PermissionModal.svelte` was passing only session-granted tools when reconnecting after a permission approval, silently dropping `config.auto_granted_tools`. Fixed to merge both sets, matching the behaviour of every other `start_claude` call site.
- **Add mid-session watchdog**: A watchdog thread now kills the Claude Code process if a user message is sent but no `Result` arrives within 5 minutes. This triggers the existing disconnect/error flow so the user is notified and can reconnect. A generation counter ensures watchdogs from previous sessions exit cleanly when a new session starts.

## Test plan

- [ ] Send a message and verify the textarea is disabled and the stop button is visible while Claude is processing
- [ ] Verify the textarea re-enables after Claude finishes responding
- [ ] Enable a tool in default permissions (e.g. Read), start a session, trigger a permission approval for another tool, approve it — verify the previously auto-granted tool is no longer re-prompted
- [ ] Verify all existing tests pass (`./check-all.sh`)

+/**
+ * PermissionModal Component Tests
+ *
+ * Tests the pure helper functions used by the PermissionModal component.
+ *
+ * What this component does:
+ * - Displays pending permission requests from Claude Code
+ * - Allows the user to approve or dismiss permission requests
+ * - On approval, reconnects Claude with the newly granted tools merged with
+ *   `auto_granted_tools` from config (bug fix: issue #198)
+ * - Restores conversation context after reconnecting
+ *
+ * Manual testing checklist:
+ * - [ ] Permission modal appears when Claude requests a tool not in allowed_tools
+ * - [ ] All permissions are pre-selected by default when modal opens
+ * - [ ] "Select All" and "Select None" buttons work correctly
+ * - [ ] "Already Granted" badge appears for tools already in the session grant list
+ * - [ ] Approving permissions reconnects Claude and restores conversation context
+ * - [ ] After reconnecting, auto_granted_tools are still respected (no re-prompting)
+ * - [ ] Dismissing the modal clears pending permissions without reconnecting
+ * - [ ] Enter key approves selected permissions
+ * - [ ] Escape key dismisses the modal
+ * - [ ] Character enters "permission" state when modal appears
+ * - [ ] Input details are shown in a collapsible "View details" section
+ *
+ * Note: The `handleApproveAndReconnect` function cannot be unit tested here
+ * because it depends on Tauri IPC calls (`invoke("stop_claude")`,
+ * `invoke("start_claude")`, `invoke("send_prompt")`). The critical bug fix
+ * (including `auto_granted_tools` in the reconnect's `allowed_tools`) is
+ * covered by the `buildAllowedToolsList` tests below, which replicate the
+ * exact merging logic from the component.
