feat: add doctor and status commands to CLI

- Implemented the `doctor` command to run health checks on the claude-mem installation, with an option to output results as JSON.
- Implemented the `status` command to display the system status of claude-mem.
- Updated the `doctor` command to use `HooksDatabase` for SQLite connectivity checks.
- Removed unused session management code from the `status` command for cleaner output.
