refactor: reorganize keymaps into semantic namespaces
Restructure keybindings for improved discoverability and consistency
with WezTerm/XMonad configurations. Separate keymaps from plugin
configurations following single responsibility principle.
Changes:
- Create keymaps/ directory with semantic grouping:
- general.nix: leader setup, page navigation
- buffers.nix: buffer operations (bq, bQ, bl)
- windows.nix: window operations (ws, wv, wq, wQ, wm)
- find.nix: telescope find operations (ff, fg, fh, fc)
- git.nix: unified git operations from gitsigns/fugitive/telescope
- Adopt consistent q/Q pattern across containers:
- bq/bQ for buffer quit (current/all others)
- wq/wQ for window quit (current/all others)
- Mirrors WezTerm's LEADER+p q / LEADER+t q pattern
- Extract keymaps from plugin files:
- telescope.nix: config only, keymaps moved to find.nix
- fugitive.nix: config only, keymaps moved to git.nix
- gitsigns.nix: config only, keymaps moved to git.nix
- snacks.nix: config only, keymaps moved to buffers.nix
- maximize.nix: config only, keymap moved to windows.nix
- Remove smart-splits.nix (functionality replaced by native window ops)
- Maintain navigation on dedicated modifiers (Ctrl+arrows/PageUp/PageDown)
for consistency with WezTerm (ALT) and XMonad (Super)
