feat: add keybind cheatsheet plugin (#64)

* feat: add keybind cheatsheet * docs: refresh keybind cheatsheet preview * docs: use official generated keybind thumbnail * feat(keybind-cheatsheet): preload cached snapshots Move parser and cache ownership into an event-driven data service so the panel opens from a prepared last-known-good snapshot. Document the plugin's inspiration and independent v5 implementation.

+# Keybind Cheatsheet
+
+Keybind Cheatsheet opens a searchable Noctalia panel containing the active
+Mango, Hyprland, or Niri shortcuts. It follows split configuration files,
+formats common hardware keys, and keeps custom descriptions and hidden rows.
+

+
+## Acknowledgements
+
+Keybind Cheatsheet was inspired by the original
+[Keybind Cheatsheet for Noctalia v4](https://github.com/4rmcyt/noctalia-plugins/tree/main/keybind-cheatsheet)
+created by [blackbartblues](https://github.com/blackbartblues).
+
+This Noctalia v5 plugin is an independent implementation rather than a direct
+port. It has its own user interface, service and cache lifecycle, persistence
+model, tests, and integration with the current Noctalia plugin API.
+
+## Plugin
+
+| Field | Value |
+| --- | --- |
+| ID | `kenn/keybind-cheatsheet` |
+| Entries | Data service: `data`; bar widget: `keybinds`; panel: `cheatsheet` |
+
+`kenn` is the plugin's fixed publisher namespace, not your local Linux
+username. Copy the plugin IDs in the commands below unchanged. User-specific
+configuration paths use the portable `~/.config/...` form.
+
+## Requirements
+
+Install `hyprctl` on `PATH` when using a Hyprland Lua configuration. Mango,
+Niri, and classic Hyprland configurations do not spawn external commands.
+
+No clipboard command is required. Color paste uses Noctalia's native clipboard
+API.
+
+## Usage
+
+Enable the plugin, then add the `keybinds` widget from Noctalia's bar widget
+picker. Clicking its keyboard glyph toggles the cheatsheet.
+
+Open or close the panel without a bar widget:
+
+```sh
+noctalia msg panel-toggle kenn/keybind-cheatsheet:cheatsheet
+```
+
+Bind that command in the active compositor.
+
+Mango:
+
+```ini
+bind=SUPER,F1,spawn,noctalia msg panel-toggle kenn/keybind-cheatsheet:cheatsheet
+```
+
+Hyprland classic configuration:
+
+```ini
+bind = SUPER, F1, exec, noctalia msg panel-toggle kenn/keybind-cheatsheet:cheatsheet
+```
+
+Niri:
+
+```kdl
+Mod+F1 { spawn "noctalia" "msg" "panel-toggle" "kenn/keybind-cheatsheet:cheatsheet"; }
+```
+
+Type in the search field to filter by key, description, action, or category.
+Use the header pencil to enter edit mode. Edit mode keeps hidden bindings
+visible with muted content while descriptions and visibility are changed with
+the row's pencil and eye buttons; leaving edit mode applies those visibility
+choices to the main keymap. The palette button opens key-color controls with
+native color picking, clipboard paste, and reset actions.
+
+## Supported configuration
+
+| Compositor | Default | Parsing |
+| --- | --- | --- |
+| Mango | `~/.config/mango/config.conf` | `bind`, `axisbind`, `mousebind`, `gesturebind`, `switchbind`, `source`, and `source-optional` |
+| Hyprland classic | `~/.config/hypr/hyprland.conf` | `bind*` directives, variables, and recursive `source` paths |
+| Hyprland Lua | `~/.config/hypr/hyprland.lua` | Live `hyprctl binds -j` data plus category and description scanning through `require()` files |
+| Niri | `~/.config/niri/config.kdl` | KDL `binds` blocks, action categorization, and recursive `include` paths |
+
+Includes support `*`, `?`, and bracket glob components. Traversal is limited to
+32 levels and 256 files, and repeated paths are visited once to stop cycles.
+
+Category comments use the same forms as the earlier Noctalia plugin:
+
+```ini
+# Applications
+bind=SUPER,T,spawn,foot #"Terminal"
+```
+
+```ini
+# 1. Applications
+bind = SUPER, T, exec, foot #"Terminal"
+```
+
+```kdl
+// #"Applications"
+Mod+T hotkey-overlay-title="Terminal" { spawn "foot"; }
+```
+
+Hyprland Lua category scanning recognizes `-- 1. Applications` headings and
+literal `description` or `desc` fields. Concatenated descriptions such as
+`"Workspace " .. i` are treated as prefixes.
+
+## Settings
+
+| Setting | Type | Default | Description |
+| --- | --- | --- | --- |
+| `compositor` | `select` | `auto` | Detect Mango, Hyprland, or Niri, or force one parser. |
+| `mango_config` | `file` | `~/.config/mango/config.conf` | Main Mango configuration. |
+| `hyprland_config` | `file` | `~/.config/hypr/hyprland.conf` | Main classic Hyprland configuration. |
+| `hyprland_lua_config` | `file` | `~/.config/hypr/hyprland.lua` | Lua file scanned for categories. |
+| `hyprland_parser` | `select` | `auto` | Select live Lua or classic parsing. |
+| `niri_config` | `file` | `~/.config/niri/config.kdl` | Main Niri configuration. |
+| `columns` | `int` | `3` | Maximum balanced columns, from 1 to 4. |
+| `show_undescribed` | `bool` | `true` | Show bindings that have no description. |
+| `show_actions` | `bool` | `false` | Show the compositor action under descriptions. |
+| `glyph` | `glyph` | `keyboard` | Bar widget icon. |
+
+Noctalia v5 owns panel dimensions and does not expose runtime auto-height.
+This plugin uses a wide 1500 x 760 panel, scrolling, and a responsive cap on
+the requested column count.
+
+## IPC
+
+Refresh the snapshot after editing compositor configuration:
+
+```sh
+noctalia msg plugin kenn/keybind-cheatsheet:data all refresh
+```
+
+The data service refreshes even when the panel is closed. Opening and reopening
+the panel only renders the prepared snapshot. The bar entry also accepts
+`toggle` and `refresh` when a widget instance exists:
+
+```sh
+noctalia msg plugin kenn/keybind-cheatsheet:keybinds focused toggle
+noctalia msg plugin kenn/keybind-cheatsheet:keybinds focused refresh
+```
+
+For parser development, run the fixture suite inside Noctalia:
+
+```sh
+noctalia msg plugin kenn/keybind-cheatsheet:data all self-test
+```
+
+The report is logged and written to the plugin's persistent data directory as
+`selftest.json`.
+
+## Notes
+
+One event-driven data service loads the durable binding cache and parses the
+selected compositor configuration once when Noctalia loads the plugin. It then
+remains idle until settings change or a refresh is explicitly requested. It
+uses no update interval, filesystem watcher, polling loop, network request, or
+persistent subprocess. Hyprland Lua mode runs the fixed command
+`hyprctl binds -j` asynchronously.
+
+The last successful parsed snapshot is stored as `bindings-cache.json`. The
+panel reads the shared in-memory snapshot and performs no configuration I/O in
+`onOpen()`. A failed refresh keeps the previous bindings visible and reports
+the error without replacing the durable cache.
+
+Custom descriptions, hidden binding identities, and color overrides are stored
+in Noctalia's per-plugin state directory as `preferences.json`. The file
+contains no command output or configuration contents.
