`multi_replace_string_in_file` requires `explanation` for each replacement which likely is confusing because of top-level `explanation`

[ulugbekna]

repro:

1. select two consecutive function declarations
2. open chat, set haiku-4.5, and ask "add console log tracing for both function"
3. haiku wants to use the multi_replace_string_in_file, it includes the explanation for the top-level field in the object, but doesn't include the explanation per replacement. So this resulted in multiple more requests despite the changes I needed could've already been resolved.

Can we make per-replacement (inner) explanation optional?

@connor4312 does this need verification?

[connor4312]

Sure. Steps: just look at the debug log for an Anthropic model and verify the tool params don't require multiple explanations
