feat(icons): add lens-concave and lens-convex

[Muhammad-Aqib-Bashir]

Description

This PR adds two new icons: lens-concave and lens-convex.
These icons represent the two fundamental types of lenses used in science, education, physics tools, and optical UI representations.

Icon use case

• lens-concave

  • Represents light divergence in physics or educational tools.
  • Useful for UI in tutoring apps, optical simulators, VR/AR calibration, or scientific diagrams.

• lens-convex

  • Represents magnification or light convergence.
  • Suitable for UI representing magnifiers, focusing tools, camera optics, telescopes, and lab equipment.

Icon Design Checklist

Concept

• I have provided valid use cases for each icon.
• I have not added any brand or logo icon.
• I have not used any hate symbols.
• I have not included any religious, violent, or political imagery.

Author, credits & license

• The icons are solely my own creation.

Naming

• I've followed the naming conventions.
• Names describe what the icons are, not their use case.
• Meta JSON files are included at icons/lens-concave.json and icons/lens-convex.json.

Design

• Icons follow the Lucide design guidelines.
• Icons look sharp on low DPI displays.
• Icons match Lucide size, optical volume, and density.
• Icons are visually centered.
• Icons are optimized to three points of precision.

Before Submitting

• I've read the Contribution Guidelines.

There's the option to make some of those path segments more mathematically precise, e.g. making the 13.9px radii of some of the arcs 14px instead.
