feat(simulator-management): add tools to toggle iOS Simulator software and hardware keyboard

[yjmeqt]

Summary

Adds two MCP tools exposing the iOS Simulator's keyboard menu items, which have no direct xcrun simctl equivalent and were unreachable through the server.

• toggle_software_keyboard — Simulator → I/O → Keyboard → Toggle Software Keyboard (Cmd+K)
• toggle_connect_hardware_keyboard — Simulator → I/O → Keyboard → Connect Hardware Keyboard (Cmd+Shift+K)

Both delegate to a shared helper _keyboard_shortcut.ts that:

1. Resolves the simulatorId to its device name via xcrun simctl list devices --json and verifies the simulator is booted.
2. Brings Simulator.app forward with open -a Simulator.
3. Raises the window for the target simulator via an AppleScript AXRaise on the window whose title contains the device name — errors out if no matching window is found (no silent fallthrough to the frontmost window).
4. Sends the appropriate keystroke via a second osascript invocation.

Resolves #346.

Implementation notes

• Why AppleScript, not defaults write ConnectHardwareKeyboard: the defaults route is a persistent global preference that only takes effect on simulator launch; it cannot toggle a running simulator and applies to all simulators simultaneously. The AppleScript approach mirrors the manual user action exactly, takes effect immediately, and leaves no persistent state — which matches what UI-automation consumers expect. Happy to revisit if maintainers prefer defaults.
• Accessibility permission: the MCP host process needs Accessibility permission in System Settings for the osascript … tell process "Simulator" to keystroke … call to succeed. This is already a prerequisite for other UI automation tools in this repo; surfaced explicitly in both tool descriptions.
• Workflow registration: both tools are added to manifests/workflows/simulator-management.yaml so they appear in the Simulator Management workflow group in TOOLS.md / TOOLS-CLI.md.
• Docs: TOOLS.md and TOOLS-CLI.md regenerated via npm run docs:update; CHANGELOG.md gains a new ## [Unreleased] section with both entries linked to [Feature]: Add tools to toggle iOS Simulator software keyboard and hardware keyboard connection #346.

Test plan

• npm run typecheck — passes
• npm run lint — passes
• npm run format:check — passes
• npm run docs:check — passes
• npm test — 144 files / 1457 tests pass (+3 files / +17 tests over baseline); covers success path, not-found, not-booted, open-app-failed, no-window-found, osascript-failed, and exception paths for both tools
• Manual: on a booted iOS simulator with Accessibility permission granted, verify `toggle_software_keyboard` hides/shows the on-screen keyboard and `toggle_connect_hardware_keyboard` connects/disconnects the Mac keyboard input
