feat: add issue discovery by prompt command with Gemini planning

- Introduced `/issue:discover-by-prompt` command for user-driven issue discovery.
- Implemented multi-agent exploration with iterative feedback loops.
- Added ACE semantic search for context gathering and cross-module comparison capabilities.
- Enhanced user experience with natural language input and adaptive exploration strategies.

feat: implement memory update queue tool for batching updates

- Created `memory-update-queue.js` for managing CLAUDE.md updates.
- Added functionality for queuing paths, deduplication, and auto-flushing based on thresholds and timeouts.
- Implemented methods for queue status retrieval, flushing, and timeout checks.
- Configured to store queue data persistently in `~/.claude/.memory-queue.json`.
