doc: Update documentation
- Moved docs to docs/ - All documentation files moved:
- docs/KEYMAPS.md - Complete keybinding reference(rewritten)
- docs/PLUGINS.md - Plugin list

- Rewrote docs/KEYMAPS.md - Based on the actual current keymap files. Removed references to deleted plugins (flash, harpoon, dial, screenkey, persistence, LSPSaga). Updated LSP keymaps to reflect fzf-lua, DAP keymaps to reflect plugin-side registration, and added CopilotChat and g keymaps.
- Updated README.md - Fixed all doc links to docs/, removed harpoon/flash/dial/screenkey/persistence references, updated essential keymaps to current reality (fzf-lua for LSP, Snacks for navigation, <leader>dcr for debug, <leader>jd for dynamic attach), added Bun debug support mention.
