refactor: split Rust backend into sub-modules — git, theme, github, frontmatter, commands
- git.rs (1907 lines) → 7 files: mod, history, status, commit, remote, conflict, pulse - theme.rs (1075 lines) → 4 files: mod, defaults, seed, create - github.rs (886 lines) → 4 files: mod, api, auth, clone - frontmatter.rs (827 lines) → 3 files: mod, yaml, ops - lib.rs (772 lines) → lib.rs (160) + commands.rs (650) 484 tests pass, clippy clean, rustfmt clean, coverage 85.42%
