Closing — this was a large feat PR in a hot area that didn't follow issue-first. Will re-approach after upstream design discussion if there's interest. |

Type of change
What does this PR do?
Ports 9 fuzzy replacer strategies from V1 (
packages/opencode/src/tool/edit.ts) to V2 core (packages/core/src/tool/edit.ts), plus Levenshtein distance, similarity thresholds, and the disproportionate-match safety guard.The V2 core edit tool currently only supports exact string matching. This change adds fuzzy fallback strategies tried in order after exact match fails: line-trimmed, block-anchor (Levenshtein similarity), whitespace-normalized, indentation-flexible, escape-normalized, trimmed-boundary, context-aware, multi-occurrence.
