Fix ja --verbose prepending --verbose ahead of delegated subcommands, which causes jig to misinterpret Maven and Gradle options.

Use one shared helper for direct tool calls and resolution calls. Insert the flag before existing options, keeping leading subcommands first, and avoid duplicating an existing verbose option. Keep the -- operand separator intact. This also keeps jar options ahead of its file inputs.

Validation:

• The Maven/Gradle and direct-tool regressions fail against current main before the fix.
• A real jar-creation regression reproduces the CI assembly failure from appending the flag after file inputs.
• All 79 tests in the affected test classes pass.
• All 494 tests pass with the built ja and its current tool bundle.

Rebased onto current main, including jig 0.21.1.
