fix: keyword replacement handling for special characters

[kushalshit27]

🔧 Changes

Fixed keyword replacement handling for special $ sequences, which was causing corruption of keyword values containing these sequences (issue #1153).

Impact: Keyword replacement now correctly values containing special $ sequences, eliminating silent data corruption during multi-environment deployments.

• Fixes #1153

🔬 Testing

• New test cases added:

• should handle dollar-apostrophe in replacement value — Validates string replacement preserves $' sequences
• should handle dollar-apostrophe in array values — Validates array replacement preserves $' sequences in multiple array elements

📝 Checklist

• All new/changed/fixed functionality is covered by tests (or N/A)
• I have added documentation for all new/changed functionality (or N/A)
