fix: use POSIX sh for test scripts to support Alpine#2
Merged
Conversation
Alpine Linux doesn't have bash installed by default. Changed test scripts to use #!/bin/sh and POSIX-compatible syntax: - Changed shebang from #!/bin/bash to #!/bin/sh - Changed 'source' to '.' (POSIX equivalent) - Changed 'bash -c' to 'sh -c' in check commands Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The devcontainer test library requires bash. Plain alpine:3.19 doesn't have bash installed, causing test failures. Updated to use the official devcontainer base images which include bash: - Changed alpine:3.19 to mcr.microsoft.com/devcontainers/base:alpine - Changed debian:bookworm to mcr.microsoft.com/devcontainers/base:debian - Reverted test scripts back to #!/bin/bash since the test library requires it Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Alpine Linux only has
/bin/sh(busybox ash) by default, not/bin/bash. The test scripts were using bash-specific syntax which caused "no such file or directory" errors when running on Alpine.Test plan
