perf: optimize grep for simple string matching
Add literal string detection to bypass regex compilation for patterns
without metacharacters. This provides ~4x performance improvement for
common grep patterns like "ERROR" or "WARNING".
- Detect literal patterns (no regex metacharacters) at compile time
- Use bytes.Contains/strings.Contains for literal matching
- Maintain full backward compatibility and serialization format
- Add comprehensive tests and benchmarks
Benchmark results show:
- Literal matching: 107.4 ns/op (optimized)
- Regex matching: 439.2 ns/op (original)
- Direct bytes.Contains: 88.51 ns/op (baseline)
