Rename the entire "tool" concept to "script": ToolHandler → ScriptHandler,
tool_command attribute → script, tool.output → script.output, and all
related artifact filenames. Add a language attribute (shell | python,
default shell) so script nodes can run Python via python3 -c natively.

SSH git URLs (git@github.com:...) cause "invalid auth method" errors
since Daytona uses HTTPS token auth. Added ssh_url_to_https() to
convert them before cloning. Also removed the static sandbox name
config field and auto-generate unique names with timestamps to prevent
"already exists" errors on repeated runs.

unavailable, 404 if pipeline not found. Resolves spec gap #1.
