Cuong Manh Le 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.

Cuong Manh Le 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.

Cuong Manh Le 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.

Cuong Manh Le dd9f2465be internal/clientinfo: map ::1 to the right host MAC address
So queries originating from host using ::1 as source will be recognized
properly, and treated the same as other queries from host itself.

Cuong Manh Le 5897c174d3 all: fix LAN hostname checking condition
The LAN hostname in question is FQDN, "." suffix must be trimmed before
checking.

While at it, also add tests for LAN/PTR query checking functions.

Cuong Manh Le f9a3f4c045 Implement new flow for LAN and private PTR resolution
- Use client info table.
 - If no sufficient data, use gateway/os/defined local upstreams.
 - If no data is returned, use remote upstream

Cuong Manh Le 0f3e8c7ada all: include client IP if ctrld is dnsmasq upstream
So ctrld can record the raw/original client IP instead of looking up
from MAC to IP, which may not the right choice in some network setup
like using wireguard/vpn on Merlin router.

Cuong Manh Le 126477ef88 all: do not depend on vyatta-dhcpd service on EdgeOS
The only reason that forces ctrld to depend on vyatta-dhcpd service on
EdgeOS is allowing ctrld to watch lease files properly, because those
files may not be created at the time client info table initialized.

However, on some EdgeOS version, vyatta-dhcpd could not start with an
empty config file, causing restart loop itself, flooding systemd log,
making the router run out of memory.

To fix this, instead of depending on vyatta-dhcpd, we should just watch
for lease files creation, then adding them to watch list.

While at it, also making ctrld starts after nss-lookup, ensuring we have
a working DNS before starting ctrld.

Cuong Manh Le 4896563e3c Various improvements and bug fixes
- Watch more events for lease file changes
 - Improving network up detection by using bootstrap IPv6 along side
   IPv4 one.
 - Emitting log to notice user that ctrld is starting.
 - Using systemd wrapper to provide correct status.
 - Restoring DNS on stop on Windows.
