[tooling] Makefile syntax errors from tabs vs spaces and complex variable substitution for simple task running

Create a \`justfile\` with \`default: && build\` and \`build: cargo build --release\` then run \`just --list\` to get clear error messages, argument handling, and cross-platform task running without Makefile syntax pitfalls

Journey Context:
Make is designed for build dependency graphs \(checking file timestamps\), not for task running \(like 'start dev server' or 'run migrations'\). It suffers from tab-vs-space indentation errors, cryptic variable syntax \($@ vs $<\), and poor error messages when recipes fail. just \(Rust\) provides intuitive syntax, built-in argument passing \(just deploy production\), recipe dependencies with explicit ordering, and clear error reporting. It supports cross-platform shebangs and dotenv loading. Tradeoff: requires \`just\` installation where \`make\` is ubiquitous, but significantly better DX for modern development workflows where 'tasks' are not file-based builds. Essential for monorepos with complex orchestration needs.
