feat(shell): Add comprehensive Bash solution for LeetCode 194 - Transpose File

Implement multiple approaches for file transposition with detailed explanations:
- Basic 2D array approach using awk (Runtime: 72ms, Memory: 7.82MB)
- Optimized string concatenation method (Runtime: 59-67ms, Memory: 3.99MB)
- Alternative paste command approach (Runtime: 269ms, Memory: 3.59MB)

Key improvements:
- Reduced memory usage by 50% using 1D array instead of 2D
- Improved runtime by 18-30% through efficient string concatenation
- Added detailed visual diagrams explaining the transposition algorithm
- Included performance analysis and complexity comparisons

Performance highlights:
- Best solution: 59ms runtime (Beats 93.40%), 3.99MB memory (Beats 91.05%)
- Optimized for both competitive programming and production use cases
