feat: add complex daily tasks (bash -c, osascript) with 6 bug fixes

End-to-end tested across WebSocket, iOS Simulator, and Android Emulator.

Changes:
- RunCommandExecutor: safety blocklist, 120s timeout, working dir support
- IntentRecognizer: 30+ complex quick paths (scripts, macOS automation)
- Ollama prompts: bash -c and osascript -e format examples
- ResultWidget: smart terminal/script/AppleScript labels, timeout/blocked cards
- ChatPage: context-aware processing messages, categorized welcome

Bug fixes:
- #1 Device pairing blocking simple auth fallback
- #2 Missing auth_required handler in Flutter
- #3 Token algorithm mismatch (SHA256 vs simple hash)
- #4 PermissionManager denying all tasks
- #5 Capability args type corruption (List→String via toString)
- #6 Capability executor 30s timeout too short

Test results: 25/26 passed (1 expected block), 0 failures
