[BUG] No Structured Logging, Uses println!

[olddev94]

Project

vgrep

Description

The codebase uses println! for all output (264 occurrences) instead of a structured logging framework. This makes it impossible to:

• Control log levels
• Filter output
• Log to files
• Integrate with observability tools
• Debug in production

Error Message

None - missing feature.

Steps to Reproduce

1. Run any vgrep command
2. Output goes directly to stdout

2. Configurable log levels (error, warn, info, debug, trace)
3. Option to log to file
4. Structured JSON logging for machine parsing
5. Timestamps on log entries

Actual Behavior

1. All output via println!
2. No log levels
3. No log file support
4. No machine-readable format
5. No timestamps
