feat(keybind-cheatsheet): update to v0.2.2 data service architecture and bug fixes

[cheerfulScumbag]

Plugin

• Id: kenn/keybind-cheatsheet
• New plugin
• Update to an existing plugin (version bumped in plugin.toml)

What it does

This update introduces a major architectural refactor to resolve host CPU callback timeouts and fixes reported community issues:

1. Data Service Architecture (service.luau):

   • Offloads configuration parsing and cache ownership to a background service ([[service]] id = "data").
   • Panel opening (panel.luau) is now instant (0ms) and renders pre-parsed snapshots from memory without performing synchronous file I/O.
   • Eliminates polling timers, watchers, and panel-tick schedulers.

2. Bug Fixes:

   • Fixes [keybind-cheatsheet][BUG] Panel blank on Niri #268 (Panel blank on Niri): Solves the onOpen() callback CPU budget timeout that caused blank panels on startup. Added support for single-quoted include directives (include './path.kdl').
   • Fixes [keybind-cheatsheet][BUG] Keybinding category is ignored for binds with a multiline description #193 (Hyprland Lua categories): Added single-pass Lua string literal extraction (extractLuaStringLiterals) to properly assign categories for empty string prefix concatenations ("" .. "Bar"), multiline assignments, and concatenated descriptions.
   • Memory Leak Protection: Added explicit dynamic callback cleanup (resetCallbacks()) in panel.luau on panel close and plugin exit.

3. Metadata & API:

   • Updated plugin_api = 9 for Noctalia v5 compatibility.

---

Note for @rylos: Once this v0.2.2 release is merged, PR #333 can rebase on top of this clean baseline to add your Niri 3x parsing speedup and 15s refresh timeout recovery!

External dependencies

• hyprctl (used only for Hyprland Lua live bind queries)

Testing

• Tested on Niri
• Tested on Hyprland
• Tested on Sway
• Tested on another compositor:
• Noctalia version tested against: v5.0.0
• Plugin API level: 9

Screenshots / Videos

No visual changes to the UI surface. Rendered keybinding layout remains identical to v0.2.1.

Checklist

• The directory name matches the part of id after the / in plugin.toml exactly.
• It ships plugin.toml, README.md, thumbnail.webp, and translations/en.json.
• README.md follows the README template, documents every entry id and dependency, and includes exact panel IPC commands and launcher prefixes where applicable.
• I created thumbnail.webp with the thumbnail generator.
• version follows semver and is bumped in this PR; plugin_api is the oldest API level this plugin requires.
• Every non-English translation in this PR uses a locale supported by Noctalia core, and I can read, write, and understand that language well enough to review and maintain it (no unreviewed machine/LLM translations).
• I did not edit catalog.toml; CI generates it.
• This PR touches exactly one plugin directory.

Code review attestation

• The code is readable and not obfuscated, minified, or generated.
• It does not download and execute remote code.
• Every network call, filesystem write, and spawned process is something the description above accounts for.
• I have the right to publish this code under the license declared in plugin.toml.
