fix: preserve fast-format arguments

[jbeckwith-oai]

Summary

• resolve relative path-list inputs before changing to the repository root
• forward every formatter argument after the path-list file
• add process-level regression coverage for both behaviors

Scope and compatibility

Affected paths are scripts/fast-format and test/scripts/fast_format_test.rb. The direct consumer is the developer fast-format workflow. Both files are handwritten repository artifacts, not generated output. This does not change the public SDK API, runtime transport, wire formats, dependencies, supported Ruby versions, or generated code.

Validation

• focused regression test: 2 runs, 5 assertions, passing
• script subsystem: 76 runs, 611 assertions, passing
• repository lint: 2,715 files, no offenses
• Sorbet: no errors
• RBS validation: 1,236 files, no errors
• Bash syntax and git diff --check: passing
• thermo-nuclear code-quality review: no findings
• full suite with the documented mock: 1,089 runs, 9,793 assertions, 0 failures, 1 pre-existing realtime proxy error; the identical 7-test/26-assertion error reproduces on base commit 8977731
