Initial commit: kmod-tui v1 — kernel module inspector TUI

Features:
- Browse all loaded kernel modules from /proc/modules
- Two-pane layout: scrollable list + detail pane
- Full-screen detail view with modinfo, parameters, holders
- Vim-style navigation (j/k, Enter, /, s, r, ?, q)
- Edge-scrolling (cursor moves freely, viewport follows)
- Filter by module name AND dependents (used_by)
- Sort by name, size, refcnt, or dependents count
- Lazy modinfo fetching (shells out only on selection)
- 13 unit tests (parser, filter, scroll logic)

Tech: Rust + ratatui + crossterm
