The 9-strategy chain (inspired by OpenCode): The 8-strategy chain (inspired by OpenCode), tried in order:
1. Exact match - Direct string comparison 1. Exact match - Direct string comparison
2. Line-trimmed - Strip leading/trailing whitespace per line 2. Line-trimmed - Strip leading/trailing whitespace per line
3. Block anchor - Match first+last lines, use similarity for middle 3. Whitespace normalized - Collapse multiple spaces/tabs to single space
4. Whitespace normalized - Collapse multiple spaces/tabs to single space 4. Indentation flexible - Ignore indentation differences entirely
5. Indentation flexible - Ignore indentation differences entirely 5. Escape normalized - Convert \\n literals to actual newlines
6. Escape normalized - Convert \\n literals to actual newlines 6. Trimmed boundary - Trim first/last line whitespace only

Multi-occurrence matching is handled via the replace_all flag.
