fix: adjust strange spacing in agent.rs

[alexhancock]

Noticed this strange spacing issue in agent.rs when working on something else, and corrected it to make the code easier to read

This is the only actual change, and still passes the formatter

Pull request overview

This PR fixes indentation inconsistencies in the reply_internal function's async stream block and improves error message clarity. The strange spacing issue involved code that was indented with excessive spaces (~20 columns) instead of following standard Rust 4-space indentation conventions. Additionally, the PR adds "trying to compact" to an error message for consistency with similar error handlers elsewhere in the codebase.

• Corrects indentation throughout a 350-line async stream block to use standard 4-space indentation
• Improves error message specificity when compaction fails to match the pattern used at line 882

I noticed that too, but neither my editor nor cargo fmt would budge

I think the real problem is that reply_internal is too nested and then our line length and format start to conflict. but the streaming setup makes it hard to refactor

this whitespace change makes it I think how it should be and still passes the formatter

so we may not get automatic corrections if it gets messed up again, but seems better than current state?
