fix: preserve gh run view passthrough args

[tsubasakong]

Summary

• preserve raw passthrough for flag-only forms like gh run view --log-failed --job <job-id> by checking passthrough flags before extracting a positional run ID
• treat short -j / -a forms the same as --job / --attempt when parsing gh run view arguments
• add regression tests covering short-flag and flag-only argument combinations

Fixes #416.

Validation

• cargo fmt --all --check
• cargo clippy --all-targets
• cargo test

Hi! Thanks for the contribution! Since March 6, all PRs should target the develop branch instead of master (see CONTRIBUTING.md).

Could you update the base branch? Click Edit at the top right of this PR and change it from master to develop.

Thanks!

Updated this PR to target develop and rebuilt it on top of current develop. The remaining diff is now just the passthrough-order + short-flag (-j / -a) fix, with local cargo fmt --all --check, cargo clippy --all-targets, and cargo test all passing.
