fix: Prevent shell/Python injection in Codespaces, Render, and FluidStack (#252)
GitHub Codespaces scripts embedded API keys directly into heredocs sent
over SSH, allowing single-quote breakout for command injection. Fixed by
adding upload_file/run_server/inject_env_vars helpers to Codespaces lib
and using safe temp-file-upload pattern (matching Railway/Render).

Render claude.sh and openclaw.sh built JSON config via unescaped heredocs.
Fixed by using shared setup_claude_code_config/setup_openclaw_config
helpers which properly json_escape values.

FluidStack had triple-quote injection in SSH key registration (pub_key
embedded in Python triple-quotes) and missing single-quote validation in
create_server env var checks. Fixed by reading values via stdin/argv
instead of string interpolation, and added single-quote to validation.
