feat: add bookmarks plugin

[dunarand]

Plugin

• Id: dunarand/bookmarks
• New plugin
• Update to an existing plugin (version bumped in plugin.toml)

What it does

Allows users to create a list of bookmarks that each get a glyhp, a label, a shell command to execute, and an optional description. Allows for 1 level deep nesting by using "folders".

Saved bookmarks are written to either the default location $NOCTALIA_STATE_HOME/plugins/data/dunarand/bookmarks/data.json, or the user can specify the file/location.

The panel can be opened via

noctalia msg panel-toggle dunarand/bookmarks:panel

or by using the bar widget shipped with the plugin.

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

Plugins run as trusted, unsandboxed Luau in the user's session. Confirm:

• 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.

Converted the PR to draft because I thought I've included all the features I wanted but came up with two improvements. I'll mark it "Ready for review" after I ship the features:

1. IPC directly into search mode: noctalia msg panel-toggle dunarand/bookmarks:panel search
2. Bookmarks can be put into or out of folders in edit mode > drag & drop
