Contain local-dev env state inside .devcontainer/#1
Merged
Conversation
Wire `.devcontainer/.env` into both Compose (auto-discovery) and the dev container itself (`runArgs --env-file`), with a host-side `initializeCommand` that creates the file from the template before `docker run` and strips CRLF for Windows/WSL. Adds Taskfile env:* commands, an env-check library + MOTD warnings for drift and unfilled required keys, and a lefthook pre-commit guard against accidentally staging the gitignored .env.

Quiet ShellCheck SC2001 ("use parameter expansion instead of sed")
without changing behavior. The awk form is also slightly cleaner.
