ChemSearch v1.1.0 - Groq AI, Autosuggestions fix etc.

Added

• Groq AI Integration: Added Groq as an alternative AI provider for chemical descriptions. Users can now choose between Google Gemini and Groq. Note that Groq uses the gpt-oss-120b model. Add your Groq API key from https://console.groq.com/keys.
• 3D Visualization Improvements: The 3D model viewer now pre-fetches SDF data via the PubChem API for smoother, offline-ready rendering using a local 3Dmol.js instance.
• Copy to Clipboard: Introduced ClickableIdentifier to allow quick copying of CID, CAS, Molecular weight, IUPAC name etc.
• Made links to AI provider website visitable.
• Added version number in the 'About' section of settings.

Changed

• App signing - Release builds are now signed with a keystore for production distribution.
• Updated versionCode to 2 and versionName to 1.1.0.
• UI/UX Redesign:
  • Redesigned CompoundHeader with a modern look and prominent typography.
  • Updated the Settings sheet with better organization and a new "About" section.
• Improved Search: Fixed z-index issues where search suggestions were being covered by other UI components.

Fixed

• Fixed 3D model viewer reliability issues by moving to local SDF data handling. (3D viewer still needs some work, as it's not working properly in some devices)
• Resolved glitches in the search suggestion overlay.
