Module git_tui 

Git TUI — interactive overlay for git status, diff viewing, staging, commit.

Module layout (built incrementally across tasks 11a/11b):

• diff_doc — unified diff parser + whitespace/formatting filters (pure)
• state — git status --porcelain -z parser (pure)
• keys — keymap → GitKeyAction (pure)
• git_io — thin std::process::Command wrappers around git (impure)
• render — ratatui pane layout + pairing math (pure layout, impure draw)

GitTuiState here is the interactive overlay’s source of truth — it composes the pure data modules above and exposes mutating methods that shell out to git_io for state changes (add/restore --staged/commit).
