--dry-run-tools flag for non-interactive pipelines

[menshiDev]

When piping inputs via stdin (cat diff.patch | gemini --pipe), it’s awesome for code reviews, but risky when dynamic tools are registered.
Can we get a strict --dry-run-tools flag that prints intended tool calls and file diffs to stdout as JSON without executing anything?
