Use portable shebang in all shell scripts

[skallet]

Summary

• Replace #!/bin/bash with #!/usr/bin/env bash in all 13 shell scripts
• #!/bin/bash assumes bash lives at /bin/bash, which isn't true on NixOS, FreeBSD, or macOS with Homebrew
• #!/usr/bin/env bash is the portable, POSIX-friendly alternative

• tests/subagent-driven-dev/run-test.sh
• tests/subagent-driven-dev/*/scaffold.sh (2 files)

Test plan

• Verify scripts remain executable on Linux
• No functional changes — only the shebang line is modified

📝 Walkthrough

Walkthrough

This pull request updates the shebang line in twelve bash scripts across the skills and tests directories from #!/bin/bash to #!/usr/bin/env bash. This change improves script portability by using the environment to locate bash instead of assuming it exists at a fixed path.

Poem

🐰 A hop through scripts both far and wide,
Where bash shebangs cast off their pride!
From fixed paths to env's embrace,
These scripts now run in any place.
Portability springs forth with glee! 🌱
