Fix Copilot CLI installer to use default version instead of latest

[Copilot]

The Copilot CLI installer was downloading latest instead of the pinned default version (0.0.382) when no version was explicitly specified in workflow frontmatter.

Root Cause

The installer command used export VERSION=X && sudo bash script.sh, which doesn't preserve environment variables in sudo by default:

# Before - VERSION not passed to sudo environment
export VERSION=0.0.382 && sudo bash /tmp/copilot-install.sh

# After - VERSION passed directly to sudo
sudo VERSION=0.0.382 bash /tmp/copilot-install.sh

Changes

• pkg/workflow/copilot_srt.go: Updated installer command to pass VERSION directly to sudo
• pkg/workflow/copilot_installer_test.go: Updated test assertions to verify new command format
• 48 workflow lock files: Recompiled to apply fix across all workflows

The installer now correctly uses DefaultCopilotVersion when no version is specified, preventing unexpected version drift to latest releases.

Original prompt

Make sure that the install copilot cli is using the default version when it is not specified in the frontmatter (not latest by default)
