Add WordLex (offline dictionary) extension

[vedesh-padal]

This Pull Request introduces the WordLex offline dictionary extension to the Vicinae ecosystem.

WordLex is a blisteringly fast, offline-first English dictionary and thesaurus powered by the comprehensive Open English WordNet (OEWN) 2025 database (~150,000+ words, 120,000+ synsets).

This extension brings instant dictionary lookups, synonyms, antonyms, and lexical relations directly to your keyboard launcher without any external API calls or internet dependencies.

🌟 Features Included

• Prefix Search (search-dictionary): Lightning-fast type-ahead search through 150k+ words. It loads the top 5 results' full detail inline, while seamlessly falling back to a compact search definition for lower results to completely bypass UI blocking.
• Define Clipboard Word (define-clipboard): Instantly look up the word in your clipboard or active text selection and display its detailed entry in a full-screen Detail view.
• Random Word (random-word): Fetch a random interesting word from the database—perfect for vocabulary building.
• Full Markdown Detail Support: Renders pronunciation, part-of-speech groupings, definitions, real-world examples, and semantic relations (Hypernyms, Hyponyms, Meronyms, Holonyms) inside Vicinae's native markdown widget.
• Command Actions:
  • Enter: Navigate to a dedicated full-screen markdown view.
  • Cmd+C: Copy the clean formatted definition.
  • Cmd+Shift+P: Paste the looked-up word directly into your frontmost active window.
  • Cmd+W: Cross-reference the word instantly on Wiktionary.
  • Cmd+O: Launch/Focus the native WordLex GUI desktop app with the searched word pre-focused.

🔌 Prerequisites & Integration Details

To maintain a zero-duplication database model, the extension connects to the locally installed WordLex desktop app's background service.
Download it from the GitHub Releases page

• Requires the desktop app to be installed (version v2.0.0+).
• The extension automatically spawns wordlex --service as a lightweight, detached background daemon (~37MB RAM).
• Communicates via local REST endpoints, delivering blazing-fast performance without spawning blocking subprocesses on every keystroke.

Hey @aurelleb,

I've been using Vicinae on Linux for a while now (switched from Windows about a year ago, missed having Raycast, and Vicinae has been a lifesaver). I wanted to experiment with building my first extension for it, so I put this together.

It's an offline dictionary extension that queries my app, WordLex (which uses the offline OEWN 2025 SQLite database). I've tested it locally to make sure the building (vici build), typechecking, and linting all pass completely clean.

Since it's my first PR here. Whenever you get a chance, take a look and approve...

Really appreciate all the work you've put into Vicinae!
