Disable BlockAnchorReplacer for better edit tool #2433
Description
Currently opencode fails a lot more often than Claude Code when doing edits. With fails I mean the output has syntax errors. I think this is caused by the tool BlockAnchorReplacer string replacement tool
https://github.com/sst/opencode/blob/8426a0d59502844345516b8ca3d6d91b4e6aec90/packages/opencode/src/tool/edit.ts#L600
opencode often does a string replacement and it inserts double ending branches, causing syntax errors, it then tries to do another search and replace to fix it and it gets an error "search and replament cannot be the same"
Often Claude will try to make a string replacement with an incorrect search string and opencode will accept the search string anyway and cause a syntax error, usually because of double ending brackets. I think this is caused by the BlockAnchorReplacer tool.
