## Summary of the Pull Request
This PR replaces the original Mages-based expression evaluation engine
with a WinRT-wrapped version of Exprtk in the CmdPalCalculator module.
### Key Changes
**Expression Engine:**
- All expression parsing and evaluation now use Exprtk (via a WinRT
wrapper) instead of Mages.
**Base Conversion Handling:**
- Since Exprtk does not support non-decimal (binary, octal, hexadecimal)
input natively, added logic to convert all such inputs to decimal before
evaluation.
**Code Structure:**
- The overall logic and API surface remain unchanged except for the
engine and base conversion handling.
- All previous Mages references and dependencies have been removed.

**WARNING:** This PR will probably blow up all in-flight PRs
at some point in the early days of CmdPal, two of us created seperate
`Exts` and `exts` dirs. Depending on what the casing was on the branch
that you checked one of those out from, it'd get stuck like that on your
PC forever.
Windows didn't care, so we never noticed.
But GitHub does care, and now browsing the source on GitHub is basically
impossible.
Closes#38081
