54f58cc2e5 feat: capitalize all log messages for better readability
Capitalize the first letter of all log messages throughout the codebase
to improve readability and consistency in logging output.

Key improvements:
- All log messages now start with capital letters
- Consistent formatting across all logging statements
- Improved readability for debugging and monitoring
- Enhanced user experience with better formatted messages

Files updated:
- CLI commands and service management
- Internal client information discovery
- Network operations and configuration
- DNS resolver and proxy operations
- Platform-specific implementations

This completes the final phase of the logging improvement project,
ensuring all log messages follow consistent capitalization standards
for better readability and professional appearance.

d88c860cac Add explanatory comments for variable overwrites and code flow decisions
This commit adds detailed explanatory comments throughout the codebase to explain
WHY certain logic is needed, not just WHAT the code does. This improves code
maintainability and helps developers understand the reasoning behind complex
decisions.

Key improvements:
- Version string processing: Explain why "v" prefix is added for semantic versioning
- Control-D configuration: Explain why config is reset to prevent mixing of settings
- DNS server categorization: Explain LAN vs public server handling for performance
- Listener configuration: Document complex fallback logic for port/IP selection
- MAC address normalization: Explain cross-platform compatibility needs
- IPv6 address processing: Document Unix-specific interface suffix handling
- Log content truncation: Explain why large content is limited to prevent flooding
- IP address categorization: Document RFC1918 prioritization logic
- IPv4/IPv6 separation: Explain network stack compatibility needs
- DNS priority logic: Document different priority levels for different scenarios
- Domain controller processing: Explain Windows API prefix handling
- Reverse mapping creation: Document API encoding/decoding needs
- Default value fallbacks: Explain why defaults prevent system failures
- IP stack configuration: Document different defaults for different upstream types

These comments help future developers understand the reasoning behind complex
business logic, making the codebase more maintainable and reducing the risk of
incorrect modifications during maintenance.

fc527dbdfb all: eliminate usage of global ProxyLogger
So setting up logging for ctrld binary and ctrld packages could be done
more easily, decouple the required setup for interactive vs daemon
running.

This is the first step toward replacing rs/zerolog libary with a
different logging library.

b002dff624 internal: only delete old ipv6 if it is non-link local

c1e6f5126a internal/clientinfo: watch NDP table changes on Linux
So with clients which only use SLAAC, ctrld could see client's new ip as
soon as its state changes to REACHABLE.

Moreover, the NDP listener is also changed to listen on all possible
ipv6 link local interfaces. That would allow ctrld to get all NDP events
happening in local network.

51b235b61a internal/clientinfo: implement ndp listen
So when new clients join the network, ctrld can really the event and
update client information to NDP table quickly.
