- justfile: add build-linux, build-windows, build-all (output to dist/)
- .gitignore: cover ctask, ctask-*, dist/
- scripts/install.sh + scripts/uninstall.sh: POSIX equivalents of .ps1
- remove WorkspacePath metadata field (no production readers; legacy
task.yaml files continue to parse silently)
Linux smoke-test on WSL/container pending.
See audit-report.md and v0.5.1-spec.md.
