feat(api): Enhance NodeDiscover with subnet auto-detection and discovery cancellation

- Updated NodeDiscover to accept an optional subnet parameter, with auto-detection of local networks if none is provided.
- Removed support for IP list format in NodeDiscover request body.
- Implemented discovery cancellation functionality with NodeDiscoveryCancel endpoint.
- Improved error handling and response messages for better clarity.

feat(cluster): Add operation tracking for cluster bootstrap process

- Integrated operations manager into cluster manager for tracking bootstrap progress.
- Refactored Bootstrap method to run asynchronously with detailed progress updates.
- Added methods to wait for various bootstrap steps (etcd health, VIP assignment, control plane readiness, etc.).

fix(discovery): Optimize node discovery process and improve maintenance mode detection

- Enhanced node discovery to run in parallel with a semaphore to limit concurrent scans.
- Updated probeNode to detect maintenance mode more reliably.
- Added functions to expand CIDR notation into individual IP addresses and retrieve local network interfaces.

refactor(node): Update node manager to handle instance-specific configurations

- Modified NewManager to accept instanceName for tailored talosconfig usage.
- Improved hardware detection logic to handle maintenance mode scenarios.

feat(operations): Implement detailed bootstrap progress tracking

- Introduced BootstrapProgress struct to track and report the status of bootstrap operations.
- Updated operation management to include bootstrap-specific details.

fix(tools): Improve talosctl command execution with context and error handling

- Added context with timeout to talosctl commands to prevent hanging on unreachable nodes.
- Enhanced error handling for version retrieval in maintenance mode.
