…line comment parsing Two improvements: 1. _build_args_str() was duplicated identically in both dds/providers/azure/container.py and dds/builders/docker.py. Moved the canonical implementation to dds/utils/shell.build_args_str() (with shell-quoting via shlex.quote — see PR digitalforgeca#1 for the safety fix). Both original sites now import and delegate to the shared version. Module-level _build_args_str aliases kept for backward compatibility. 2. load_env_file() in dds/secrets.py did not strip inline comments from unquoted values, so a line like: DATABASE_URL=postgres://localhost/mydb # local dev only would produce 'postgres://localhost/mydb # local dev only' as the value. This is incorrect — standard .env file parsers (dotenv et al.) strip inline comments from unquoted values. Quoted values are left untouched (the comment is considered part of the value when quoted). Added stripping for ' #' and '\t#' comment separators on unquoted values.

Summary
Adds test coverage for the two new behaviours introduced in PR #2.
Depends on PR #2 (
fix/build-args-dedup-env-file-comments) — merge that first.1.
