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.

4792183c0d Add comprehensive documentation to CLI components and core functionality
This commit extends the documentation effort by adding detailed explanatory
comments to key CLI components and core functionality throughout the cmd/
directory. The changes focus on explaining WHY certain logic is needed,
not just WHAT the code does, improving code maintainability and helping
developers understand complex business decisions.

Key improvements:
- Main entry points: Document CLI initialization, logging setup, and cache
  configuration with reasoning for design decisions
- DNS proxy core: Explain DNS proxy constants, data structures, and core
  processing pipeline for handling DNS queries
- Service management: Document service command structure, configuration
  patterns, and platform-specific service handling
- Logging infrastructure: Explain log buffer management, level encoders,
  and log formatting decisions for different use cases
- Metrics and monitoring: Document Prometheus metrics structure, HTTP
  endpoints, and conditional metric collection for performance
- Network handling: Explain Linux-specific network interface filtering,
  virtual interface detection, and DNS configuration management
- Hostname validation: Document RFC1123 compliance and DNS naming
  standards for system compatibility
- Mobile integration: Explain HTTP retry logic, fallback mechanisms, and
  mobile platform integration patterns
- Connection management: Document connection wrapper design to prevent
  log pollution during process lifecycle

Technical details:
- Added explanatory comments to 11 additional files in cmd/cli/
- Maintained consistent documentation style and format
- Preserved all existing functionality while improving code clarity
- Enhanced understanding of complex business logic and platform-specific
  behavior

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

ddbb0f0db4 refactor: migrate from zerolog to zap logging library
Replace github.com/rs/zerolog with go.uber.org/zap throughout the codebase
to improve performance and provide better structured logging capabilities.

Key changes:
- Replace zerolog imports with zap and zapcore
- Implement custom Logger wrapper in log.go to maintain zerolog-like API
- Add LogEvent struct with chained methods (Str, Int, Err, Bool, etc.)
- Update all logging calls to use the new zap-based wrapper
- Replace JSON encoders with Console encoders for better readability

Benefits:
- Better performance with zap's optimized logging
- Consistent structured logging across all components
- Maintained zerolog-like API for easy migration
- Proper field context preservation for debugging
- Multi-core logging architecture for better output control

All tests pass and build succeeds.

c6365e6b74 cmd/cli: handle stop signal from service manager
So using "ctrld stop" or service manager to stop ctrld will end up with
the same result, stopped ctrld with a working DNS, and deactivation pin
code will always have effects if set.

47a90ec2a1 cmd/cli: re-fetch pin code during deactivation checking
So if the pin code was updated/removed, it will be checked correctly by
ctrld during stop/uninstall commands.

5af3ec4f7b cmd/cli: ensure DNS goroutines terminated before self-uninstall
Otherwise, these goroutines could mess up with what resetDNS function
do, reverting DHCP DNS settings to ctrld listeners.

8b98faa441 cmd/cli: do not mask err argument of selfUninstall
The err should be preserved, so if we passed the error around, other
functions could still check for utility error code correctly.

905f2d08c5 cmd/cli: fix reset DNS when doing self-uninstall
While at it, also using "ctrld uninstall" on unix platform, ensuring
everything is cleanup properly.
